ex1712

#include <stdio.h>

char *binbin(unsigned n);

int main()
{
    unsigned bshift,x;

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

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

    return(0);
}

char *binbin(unsigned 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);
}

Output

Type a value 0 to 255: 128
0000000010000000 128
0000000001000000 64
0000000000100000 32
