C program to convert binary number to decimal

Given below is a c program to convert binary number to decimal.

Example :

1111 - Binary Number

1        1        1        1  

23       22       21       20

8        4        2        1

2³x1 + 2²x1 + 2¹x1 + 2⁰ = 8+4+2+1 = 15

101 - Binary Number

1        0        1  

22       21       20

4        2        1

2²x1 + 2¹x0 + 2⁰ = 4+0+1 = 5

void main()
{    
    long int n,i=1,d=0,m=0,l=0;
    clrscr();
    printf("Enter binary number : ");
    scanf("%ld",&n);
    while(n>0)
    {
        m=(n%10);
        n=(n/10);
        l=m*i;
        d=d+l;
        i=i*2;
    }
    printf("Decimal equivalent is : %ld",d);
    getch();
}

Output :

Enter binary number : 1111
Decimal equivalent is : 15
