Sum of digits program in C

C program to sum each digit: We can write the sum of digits program in c language by the help of loop and mathematical operation only.

Sum of digits algorithm

To get sum of each digits by c program, use the following algorithm:

• Step 1: Get number by user
• Step 2: Get the modulus/remainder of the number
• Step 3: sum the remainder of the number
• Step 4: Divide the number by 10
• Step 5: Repeat the step 2 while number is greater than 0.

Let’s see the sum of digits program in C.

Output:

Enter a number:654 Sum is=15  Enter a number:123 Sum is=6
