Program:

#include<stdio.h>
#include<conio.h>
main()
{
    long b,dec=0,j=1,rem;
    clrscr();
    printf("Enter Binary number: ");
    scanf("%ld",&b);
    while(b!=0)
    {
        rem=b%10;
        ///////////////
        dec=dec+rem*j;
        ///////////////
        j=j*2;
        ///////////////
        b=b/10;
        ///////////////
    }
    printf("\nDecimal is %ld",dec);
    getch();
}

output:
