Program to Convert Binary to Decimal - Binary to Decimal Converter Program

This is a c program to convert a binary number to decimal number. The input (binary number) should contain only zeros and ones. Binary number system represents numbers using only two digits; 0 and 1. The following is a binary to decimal converter program in C.

#include<stdio.h>
#include<string.h>

int BinToDec(int bin)
{
int rem,dec=0,base=1;
int num;
num=bin;
while(num>0)
   {
   rem = num % 10;
   dec = dec + rem * base;
   num = num / 10 ;
   base = base * 2;
   }
return dec;
}

void main()
{
int inputnum;
printf("\nEnter the binary number\n");
scanf("%d",&inputnum);
printf("Corresponding decimal number is: %d",BinToDec(inputnum));
}
