1. Explain the pass by value and pass by reference mechanisms. Give examples that show their difference.
2. Consider the function -
int f(int n, int a[]) {
Int cnt = 0;
for (int i=0; i
if (a[i] == a[0]) cnt++;

3. Implement the makeStrCopy function. Remember that, It takes a string in copies to an output string out. The signature should be void makeStrCopy(char in[], char out[]). For example - if in = "hello", after calling makeStrCopy, out should also be "hello"
4. Dynamically allocate an array of floats with 100 elements. How much memory does it take?
5. Suppose int a[] = {1, 2, 3, 4, 5, 6, 7, 8, 9}. Suppose the address of a[0] is at 6000. Find the value of the following -
a. a[8]
b. &a[5]
c. a
d. a+4
e. *(a+2)
f. &*(a+4)
6. Ash tries to implement bubble sort the following way. In particular, notice that the loop iterates on the array in reverse. Fill in the box to implement the function.
void sort(int n, int a[]) {
for (int steps=0; steps
for (int i=n-1; i>0; i--) {
///Write code here
}
}
}
7. implement the is_reverese_sorted() function to check if an array reverse sorted. For example if a = {6, 4, 3, 1}. Then is_reverse_sorted should return True
8. Modify the Selection sort function so that it sorts the array in reverse sorted order, ie. from the largest to smallest. For example reverse sorting a = {3, 4, 2, 5, 1} should result in {5, 4, 3, 2, 1}. Use the is_reverse_sorted() function to break early from the function if the array is already sorted
9. We wrote a program to find all positions of a character in a string with the strchr function. Now do the same without using strchr
10. Is there any difference in output if you call strstr(text, "a") and strchr(text, ‘a’)? Explain with examples.
Answers
There may be a difference in output between strstr(text, "a") and strchr(text, 'a'). An explanation with examples is provided to clarify the difference in behavior.
Pass by value and pass by reference are mechanisms for passing arguments to functions. In pass by value, a copy of the value is passed, while in pass by reference, the memory address of the variable is passed.
Examples illustrating their difference are provided.
The function counts the number of occurrences of the first element in the array and returns the count. When n = 5 and a = {1, 2, 1, 2, 1}, the return value is 3.
The makeStrCopy function copies the contents of the input string to the output string. It has a void return type and takes two character arrays as parameters.
To dynamically allocate an array of floats with 100 elements, it would take 400 bytes of memory (assuming each float occupies 4 bytes).
The values of the expressions are as follows: a. 9, b. 6004, c. 6000, d. 6004, e. 3, f. 6004.
The missing code to implement the bubble sort function is required to complete the implementation.
The is_reverse_sorted function checks if an array is sorted in reverse order and returns True if so.
The selection sort function is modified to sort the array in reverse sorted order, and the is_reverse_sorted function is used to optimize the sorting process.
A method to find all positions of a character in a string without using strchr is requested.

Name two-fluid technologies that make use of water.
Answers
Answer:
Fire extenguisher and refrigerator
Refrigerator : There are 5 basic components in refrigeration I.e. fluid refrigerant, a compressor which controls the flow of refrigerant; the condensor coil( on the outside of the fridge), evaporation coils( on the inside of the fridge) and something calls an expansion device.
The compressor constricts the refrigerant vapour,raising its pressure and pushes it in the coils on the outside of the refrigerator.
When the hot gas in the coils meets the cooler air temperature of the kitchen it becomes a liquid.
Now in the liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge.
The refrigerant absorbs the heat inside the fridge cooling down the air.
Last the refrigerant evaporates to a gas then flows back to the compressor where the cycle starts all over.
Fire Extinguishers: Water performs two functions; its conversion tosteam absorbs the heat, and the steam displaces the air from the vicinity of the flame. Many siimple fire extinguishers are quipped with hand pumps or sources of compressed gas to propel water through the nozzle.

Which of the following are allowed in the third section of the for loop statement?A) printf(ʺHello\nʺ);B) i++C) i+=2D) i--E) all of the above35).
Answers
The third section of a for-loop statement, also known as the update section, is responsible for updating the loop control variable. This is a crucial part of the for loop, as it helps control the number of iterations the loop goes through before it terminates.
In the given options, A) print ("Hello\n"); is a function used for displaying text on the screen and is not suitable for updating the loop control variable. Therefore, option A is not allowed in the third section of the for-loop statement.
Options B) i++, C) i+=2, and D) I-- are all valid ways of updating the loop control variable. i++ increments the variable by 1, i+=2 increments it by 2, and I-- decrements it by 1. These operations are allowed in the third section of the for-loop statement, as they effectively update the loop control variable.
In Summary, the allowed options in the third section of the for loop statement are B) i++, C) i+=2, and D) i--. Option E) "all of the above" is not correct, as option A is not allowed in this section. The main purpose of the third section is to update the loop control variable, and options B, C, and D serve this purpose effectively.

suppose you have a hard disk with 2200 tracks per surface, each track divided into 110 sectors, six platters and a block size of 512 bytes(i.e., 1 /2 kilobyte), what is the total raw capacity of the disk drive?
Answers
Suppose you have a hard disk with 2200 tracks per surface, each track divided into 110 sectors, six platters, and a block size of 512 bytes (i.e., 1 /2 kilobyte), then the total raw capacity of the disk drive is 13.4 GB.
A hard disk drive (HDD) is a data storage device that uses magnetic storage to store and retrieves digital data using one or more rigid rapidly rotating disks (platters) covered in magnetic material. A hard disk drive is a random-access memory device (RAM), meaning that data can be read or written in almost any order after the first write operation has been completed.
Suppose you have a hard disk with 2200 tracks per surface, each track divided into 110 sectors, six platters, and a block size of 512 bytes (i.e., 1 /2 kilobyte), then the total raw capacity of the disk drive is 13.4 GB. The formula to calculate the total raw capacity of the disk drive is given:
Total raw capacity = Number of surfaces × Number of tracks per surface × Number of sectors per track × Block size per sector × Number of platters
We are given: Number of surfaces = 2
Number of tracks per surface = 2200
Number of sectors per track = 110
Block size per sector = 512 bytes
Number of platters = 6
Now, let's substitute these values in the above formula:
Total raw capacity = 2 × 2200 × 110 × 512 × 6
= 13,428,480,000 bytes = 13.4 GB
Therefore, the total raw capacity of the disk drive is 13.4 GB.

Answers
A lockbox system is a system in which a company's incoming payments are directed to a post office box, rather than to the company's offices. This allows the company to process payments more efficiently, since the payments are sent directly to a bank that is authorized to receive and deposit them.
The bank will then deposit the funds into the company's account, rather than sending them to the company's offices for processing. First, it can help reduce processing time for incoming payments. Second, a lockbox system can help reduce the risk of fraud.
Since payments are sent directly to the bank, there is less chance that they will be lost, stolen, or misused. Third, a lockbox system can help improve cash flow. By reducing the time, it takes to process payments, the company can receive its funds more quickly and put them to use sooner. This can help improve the company's overall financial position.

When you touch a warm picnic table , your hand becomes warmer. Explain how energy conservation applies to this situation
Answers
When you contact a warm picnic table, this transfer occurs because your hand has a lower surface temperature than the table, which allows the heat to pass from the table to your hand. You can see how this procedure conserves energy.
Why should we conserve energy?Energy conservation is essential for limiting climate change. It helps to replace non-renewable resources with renewable energy. When there are energy shortages, energy saving is frequently more cost-effective and environmentally friendly than increasing energy output.

Answers
There are differences in the suffixes that we use in computing environments as explained in the briefing.
What is meant by computing environment?In order to process and exchange the electronic information required by the software solution, the computing environment consists of a variety of computer hardware, data storage devices, workstations, software applications, and networks.
Briefing:the Bit is 0 or 1, and 1 byte= 8 bits,
1 kilobyte=1000 bytes= 8×1000 =8000 bits where 1 kilo=10^3
1 megabyte = 1000000 bytes= 8000000 bits
where 1 mega= 10^6 bytes
thus, regardless of whether a measurement is a megabyte or a megabit, mega = 10^6, but where it differs is when converted into the last minimum measurement i.e., bits then we get the difference.
1 megabit = 1000000 bits =1000000 bits = 1000000 ÷ 8 = 125000 bytes
1 megabyte=1000000 bytes=8000000 bits

12. Explain the differences between party organization at the national level compared to the State and local level.
Answers
National party organizations have a broader scope, centralized structure, and focus on national elections and large-scale fundraising, while state and local party organizations have a narrower focus, decentralized structure, and concentrate on regional elections and grassroots fundraising.
What are the differences between party organization at the national level compared to the state and local level?Here are the differences between party organization at the national level compared to the state and local level, along with valid explanations:
Scope and Influence:- National Level: Party organizations at the national level have a broader scope and influence. They focus on shaping the party's agenda, ideology, and platform at a national scale. National parties have a significant impact on policy formulation, national elections, and setting the overall direction of the party.
- State and Local Level: Party organizations at the state and local level have a more limited scope and influence. They primarily concentrate on regional issues, local elections, and grassroots organizing. State and local parties play a crucial role in shaping local policy priorities, supporting candidates for state and local offices, and mobilizing voters within their specific jurisdictions.
Organizational Structure:- National Level: Party organizations at the national level have a centralized and hierarchical structure. They often have a national committee or executive board responsible for decision-making, resource allocation, and strategic planning. This structure allows for coordination and consistency in party activities across the entire country.
- State and Local Level: Party organizations at the state and local level have a more decentralized and grassroots-oriented structure. They consist of local party units, such as county or city committees, which have their own leadership and decision-making processes. This structure enables adaptability to local contexts and allows for greater community engagement.
Electoral Focus:- National Level: National party organizations focus on high-profile elections, particularly presidential and congressional races. They allocate significant resources, mobilize volunteers, and coordinate national campaign strategies to secure victories at the national level. Their efforts often include messaging that appeals to a broad range of voters across different states and regions.
- State and Local Level: Party organizations at the state and local level primarily concentrate on local and state elections. They aim to support candidates for governor, state legislatures, mayoral positions, county boards, and other regional offices. These organizations tailor their strategies and messaging to address specific local issues, concerns, and demographics to mobilize support within their communities.
Fundraising:- National Level: National party organizations engage in large-scale fundraising efforts. They have broader access to national donor networks, major fundraising events, and sophisticated fundraising strategies. National parties often rely on a combination of individual donations, corporate contributions, and fundraising from high-profile supporters to generate significant financial resources.
- State and Local Level: Party organizations at the state and local level rely on a mix of grassroots fundraising and localized donor networks. They often conduct community-based fundraising initiatives, such as small-scale events and door-to-door canvassing, to raise funds. While their financial resources may be comparatively limited, they emphasize connecting with local donors who are invested in their specific communities.
In conclusion, party organizations at the national level have a broader scope and influence, a centralized structure, focus on national elections, and engage in large-scale fundraising. In contrast, party organizations at the state and local level have a narrower scope, a more decentralized structure, focus on regional elections, and rely on grassroots fundraising.
