OCTAL TO BINARY CONVERSION

Consider the following I/O samples.

SAMPLE INPUT : 23

SAMPLE OUTPUT:  10011

C PROGRAM:

#include <stdio.h>
#include<math.h>
int main()
{
   long int n, dec=0, bin=0, i=0;
    scanf("%ld",&n);
    while(n)
    {
        dec+=(n%10)*pow(8,i);
        ++i;
        n/=10;
    }
    i=1;
    while(dec)
    {
        bin+=(dec%2)*i;
        dec/=2;
        i*=10;
    }
    printf("%ld",bin);
    return 0;
}

 

OUTPUT:
