Calculating the Sum of Digits in C Programming Language: A Comprehensive Tutorial

 Sum Of Digits Using C

Welcome to this tutorial where you will learn how to calculate the sum of digits using C programming language. This is a simple program that involves adding up the individual digits of a number to arrive at a sum.

In this tutorial, we will provide you with a comprehensive guide on how to calculate the sum of digits in C programming language. We will cover various methods to perform this operation, including using loops, recursion, and arrays.

You will learn how to write a C program to calculate the sum of digits in a number, and we will provide you with easy-to-understand examples and clear explanations of the process.

For instance, let's take the example of the number 7865434. To find the sum of its digits, we would add up 7 + 8 + 6 + 5 + 4 + 3 + 4, which equals 37. We will show you how to solve this problem with programming/coding using the C language.

You can also use this same logic in other programming languages to solve similar problems.

By the end of this tutorial, you will have a solid understanding of how to calculate the sum of digits using C programming language, and you will be able to apply this skill to other programming tasks.

Source Code:

 #include <stdio.h>
 #include <conio.h>
 int main()
 {
    int digit,rem,sum=0;
    printf("Enter a digit: ");
    scanf("%d",&digit);
    while(digit>0){
        rem=digit%10;
        sum=sum+rem;
        digit=digit/10;
    }
    printf("Sum of digit: %d",sum);
    return 0;
 }

Output:

Enter a digit: 7865434

Sum of digit: 37
