Requirements

Write program to display 16 bits int value in binary

Hint

The max value of 16 bits of integer is 65535.

Demo

#include <stdio.h>

char *to_binary(int n);

int main()/*from w  w  w  . ja  va 2s  . c  o  m*/
{
    int input;

    printf("Type a value 0 to 65535: ");
    scanf("%d",&input);
    printf("%d is binary %s\n",input,to_binary(input));
    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);
}
