[c-prog] Re: binary to decimal

[sharma.anandd]

I think this is the solution of your problem and this code does not uses even 
if keyword. But i have use a function.


//Program to convert a binary number to its equivalent decimal number
#include<stdio.h>
#include<conio.h>
#include<math.h>
int main()
{
 int count_digits(int);
 int num,n,R,r,dec=0;
 clrscr();
 printf("\nEnter a number in binary form : ");
 scanf("%d",&num);
 n=count_digits(num);
 while(num)
 {
  r=num%10;
  R=r*pow(2,--n);
  dec+=R;
  num=num/10;
 }
printf("\nDecimal : %d", dec);
getch();
return 0;
}
int count_digits(int num) //Function to count to digits
{
 int n=0;
 while(num)
 {
  num/=10;
  n++;
 }
 return n;
}
