Q. C# Program to Find the Sum of Digits in a Given Number.

Here you will find an algorithm and program in C# programming language to find the sum of digits in number. Now let us understand this.

Explanation : Suppose we are having number 12548 and we have to calculate the sum of digits in the given number, so here we have the following digits 1, 2, 5, 4, 8 and we will sum all these digits -> 1 + 2 + 5 + 4 + 8 and the result we get is 20 that will be our output.

START
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.

C# Program to Find the Sum Of Digits in Number

using System; 
class LFC { 
	static int sum_digit(int num) 
	{ 
	int sum = 0,rem; 
	while (num != 0) { 
		rem=num%10;
		num = num / 10; 
		sum=sum+rem; 
		} 
	return sum; 
	} 

	public static void Main() 
	{ 
		int num = 123456; 
		Console.WriteLine("Sum Of"
		+ " Digits : " + sum_digit(num)); 
	} 
} 

Output

Sum Of Digits : 21
