Binary to Decimal Conversion:

======================

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int dec,i,j;

long int binary;

clrscr();

printf("Enter binary value\n");

scanf("%ld",&binary);

i=0;

dec=0;

top:

j=binary%10;

binary/=10;

dec=dec+(j*pow(2,i));

if(binary>0)

{

i++;

goto top;

}

printf("decimal vlaue is: %d",dec);

getch();

}
