Question

Write down a program which takes input of a random number and checks if it is

an odd number or even number. If the number is even, the program performs
square of that number and inserts it in the CX register.
If the number is odd, the program converts the number into an even number, then enters
a1 value to the CX register.

Answer 1

To write a program that checks if a number is odd or even, you can use an if-else statement in C. If the number is even, the program calculates the square and stores it in the CX register. If the number is odd, it converts the number to an even number and stores it in the CX register.

Step-by-step explanation:

To write a program that checks whether a number is odd or even, you can use an if-else statement. Here's an example code snippet:

#include <stdio.h>

int main() {
int number;
printf("Enter a number: ");
scanf("%d", &number);

if(number % 2 == 0) { // checks if the number is even
int squaredNumber = number * number;
asm("movl %0, %%ecx" : "=r" (squaredNumber)); // moves the squared number to the CX register
}
else { // if number is odd
int evenNumber = number + 1;
asm("movl %0, %%ecx" : "=r" (evenNumber)); // moves the even number to the CX register
}

return 0;
}
