Introduction
I have used Code::blocks 12 compiler for debugging purpose. But you can use any C programming language compiler as per your availability.
Write C Program to convert binary number to decimal
#include <stdio.h>
#include <math.h>
//Function declartion
int convertBinaryToDecimal(long long n);
int main()
{
long long n;
printf("Enter a binary number: ");
// Inputting number from user
scanf("%lld", &n);
//Printing binary number to decimal
printf("%lld in binary = %d in decimal", n, convertBinaryToDecimal(n));
return 0;
}
int convertBinaryToDecimal(long long n)
{
int decimalNumber = 0, i = 0, remainder;
while (n!=0)
{
remainder = n%10;
n /= 10;
decimalNumber += remainder*pow(2,i);
++i;
}
return decimalNumber;
}
Result
