C Program to Convert Binary to Hexadecimal Number

In this tutorial, we will explain a simple program to convert the binary number into the hexadecimal number. We have not used any number validation in this program as it is designed for the beginners for learning purpose.

You can modify this program to validate the number entered by the user during the program execution, then the user can only enter the binary number to hexadecimal number conversion using c programming language.

Copy below c program and execute it with c compiler to see the output of the program and also start converting the number system from binary to hexadecimal number.

Enter the binary number: 10000
Equivalent hexadecimal value: 10

  1. 
    int main() {
        long int binaryval, decimalval = 0;
        printf("Enter the binary number: ");
        scanf("%ld", &binaryval);
        do {
            decimalval = (decimalval << 1) + binaryval % 10;
        } while (binaryval /= 10);
        printf("Equivalent hexadecimal value: %lX", decimalval);
        return 0;
    }
    

    You're calculating the decimal value and showing it as hex, so call it that.... and simplify the logic down by leveraging loose boolean and ditching the variables for nothing.
