Sum of digits program in C

Sum of digits program in C With Example

C program to sum each digit: Let's Make a program in C language to the sum of digits program with the help of loop and mathematical operation.

Steps to design algorithm sum of Integers

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

• Step 1: Take number by user as Input
• 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.

1. #include<stdio.h>  
2. #include<conio.h>  
3. void main()  
4. {  
5. int n,sum=0,m;  
6. clrscr();  
7. printf("Enter a number:");  
8. scanf("%d",&n);  
9. while(n>0)  
10. {  
11. m=n%10;  
12. sum=sum+m;  
13. n=n/10;  
14. }  
15. printf("Sum is=%d",sum);  
16. getch();  
17. }     

Output:

Enter a number:654
Sum is=15

Enter a number:123
Sum is=6
