Sum of digits program in C#

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 digit 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: 23  
Sum is= 5
Enter a number: 624       
Sum is= 12
