Write a assembly code function (decode) to clean the data in a variable (one byte long) from '0'. The variable address is placed in ECX

Write a function (encode) to 'ADD' an ascii 0 to a variable. The variable address is placed in ECX

Answers

The assembly code function (decode) to clean the data in a variable (one byte long) from '0'. The variable address is placed in ECX is given below:

Here's the assembly code for the two functions for variable:

; Function to clean data in a byte variable from '0'

decode:

   push ebp            ; Save base pointer

   mov ebp, esp        ; Set up new base pointer

   mov al, [ecx]       ; Load byte from variable into AL register

   cmp al, 30h         ; Compare AL with '0' character

   jb end_decode       ; If AL is less than '0', jump to end

   cmp al, 3Ah         ; Compare AL with ':' character

   jae end_decode      ; If AL is greater than or equal to ':', jump to end

   sub al, 30h         ; Subtract '0' from AL to clean the data

   mov [ecx], al       ; Store cleaned data back into variable

end_decode:

   pop ebp             ; Restore base pointer

   ret                 ; Return from function

; Function to add an ascii 0 to a variable

encode:

   push ebp            ; Save base pointer

   mov ebp, esp        ; Set up new base pointer

   mov al, [ecx]       ; Load byte from variable into AL register

fruit = "banana"
count = 0
for char in fruit:
if char == "a":
count += 1
print(count)


This code takes the word "banana" and counts the number of "a"s. Modify this code so that it will count any letter the user wants in a string that they input. For example, if the user entered "How now brown cow" as the string, and asked to count the w's, the program would say 4.

Put the code in a function that takes two parameters-- the text and the letter to be searched for. Your header will look like def count_letters(p, let) This function will return the number of occurrences of the letter.
Use a main() function to get the phrase and the letter from the user and pass them to the count_letters(p,let) function. Store the returned letter count in a variable. Print "there are x occurrences of y in thephrase" in this function.

Locality of reference.

Explanation:

In computing, The principle of locality of reference is the probability of a processor to repeatedly access the same set of memory locations within a small time interval. This reference of locality can be spatially based (repetitive usage of data within the same location on the computer memory), or temporally based (repetitive usage of a particular data or resources within a shot time interval). The ability of some computing system to perform this action increases their predictability, and efficiency of memory hierarchy use, among other abilities.

Answers

Answer:

465 ways

Explanation:

Atleast 1 girl and 1 boy

Possible combinations :

1 girl ; 3 boys = 6C1 ; 6C3

2 girls ; 2 boys = 6C2 ; 6C2

3 girls ; 1 boy = 6C3 ; 6C1

(6C1 * 6C3) + (6C2 * 6C2) + (6C3 * 6C1)

Combination formula:

nCr = n! ÷ (n-r)!r!

We can also use a calculator :

6C1 = 6

6C3 = 20

6C2 = 15

Hence,

(6C1 * 6C3) + (6C2 * 6C2) + (6C3 * 6C1)

(6 * 20) + (15 * 15) + (20 * 6)

120 + 225 + 120
