In this source code example, we will write a code to binary value to decimal number in the C programming language.

Convert Binary to Decimal in C

In this C program, we will take input from the User or console. 

#include <stdio.h>

int main()
{
    int remainder, number = 0, decimal_number = 0, temp = 1;
    printf("Enter any binary number => ");
    scanf("%d", &number);

    // Iterate over the number until the end.
    while (number > 0)
    {
        remainder = number % 10;
        number = number / 10;
        decimal_number += remainder * temp;
        temp = temp * 2;  // used as power of 2
    }

    printf("%d", decimal_number);
}

Output:

Enter any binary number => 1110
