Question

Write the function combine that takes two unsigned integers x and y, and yields a word consisting of the least significant byte of x and the remaining bytes of y. For operands x

Answer 1

Answer:

This question is incomplete. The complete question is given below:

Write a C expression that will yield a word consisting of the least significant byte of x, and the remaining bytes of y. For operands x = 0x89ABCDEF and y = 0x76543210, this would give 0x765432EF.

#include <stdio.h>

int main(void)

{

  int x = 0x89ABCDEF;

  int y = 0x76543210;

  printf("0x%x\n", (x & 0x000000FF) | (y & 0xFFFFFF00));

  return 0;

}

Explanation:

• Inside the main function, initialize variable x with 0x89ABCDEF and variable Y with 0x76543210 as asked in the requirement of this question  
• After that print the expression that will display a word consisting of the least significant byte of flax and be remaining bytes of y.

Output:

0x765432EF
