Write program to divide integer by 2 using shift operator

Hint

The >> shift operator shifts value to the right.

Any bit that's marched off the right end is discarded, and only zero bits are inserted on the left side.

Here's the format:

v = int >> count; 

int is an integer value, and count is the number of places to shift the bits to the right.

The result is stored in variable v.

The >> is guaranteed to always cut the value in half when you shift one digit to the right.

Demo

#include <stdio.h>

char *to_binary(int n);

int main()//from w ww .j  a va2s .  c o m
{
    int bshift,x;

    printf("Type a value from 0 to 255: ");
    scanf("%d",&bshift);

    for(x=0;x<8;x++)
    {
        printf("%s %d\n",to_binary(bshift),bshift);
        bshift = bshift >> 1;
    }

    return(0);
}

char *to_binary(int n)
{
    static char bin[17];
    int x;

    for(x=0;x<16;x++)
    {
        bin[x] = n & 0x8000 ? '1' : '0';
        n <<= 1;
    }
    bin[x] = '\0';
    return(bin);
}
