#include <iostream>

#include <math.h>

using namespace std;

int main()

{

    int bin,i=0,decnum=0,rem;

    cout<<"Enter a binary number: ";

    cin >>bin;

    while(bin!=0)

    {

        rem=bin%10;

        bin/=10;

        decnum=decnum+rem*pow(2,i);

        ++i;

    }

    cout<<"\nDecimal equivalent is "<<decnum;

    return 0;

}

OUTPUT:
