Question

Write a C program that right shifts an integer variable 4 bits. The program should print the integer in bits before and after the shift operation. Does your system place 0s or 1s in the vacated bits?

Answer 1

Solution :

#include<$\text{stdio.h}$>

#include<conio.h>

void dec_bin(int number) {

$\text{int x, y}$;

x = y = 0;

for(y = 15; y >= 0; y--) {

x = number / (1 << y);

number = number - x * (1 << y);

printf("%d", x);

}

printf("\n");

}

int main()

{

int k;

printf("Enter No u wanted to right shift by 4 : ");

scanf("%d",&k);

dec_bin(k);

k = k>>4; // right shift here.

dec_bin(k);

getch();

return 0;

}
