Write a c program to find out sum of digit of given number
Code 1:
1. C program to add digits of a number
2. C program for sum of digits of a number
3. C program to calculate sum of digits
#include<stdio.h>
int main(){
int num,sum=0,r;
printf("Enter a number: ");
scanf("%d",&num);
while(num){
r=num%10;
num=num/10;
sum=sum+r;
}
printf("Sum of digits of number: %d",sum);
return 0;
}
Sample output:
Enter a number: 123
Sum of digits of number: 6
Code 2:
1. Sum of digits of a number in c using for loop
#include<stdio.h>
int main(){
int num,sum=0,r;
printf("Enter a number: ");
scanf("%d",&num);
for(;num!=0;num=num/10){
r=num%10;
sum=sum+r;
}
printf("Sum of digits of number: %d",sum);
return 0;
}
Sample output:
Enter a number: 567
Sum of digits of number: 18
Code 3:
1. Sum of digits in c using recursion
#include<stdio.h>
int getSum(int);
int main(){
int num,sum;
printf("Enter a number: ");
scanf("%d",&num);
sum = getSum(num);
printf("Sum of digits of number: %d",sum);
return 0;
}
int getSum(int num){
static int sum =0,r;
if(num!=0){
r=num%10;
sum=sum+r;
getSum(num/10);
}
return sum;
}
Sample output:
Enter a number: 45
Sum of digits of number: 9

/* Source code to find ASCII value of a character entered by user */
#include <stdio.h>
int main(){
char c;
printf("Enter a character: ");
scanf("%c",&c); /* Takes a character from user */
printf("ASCII value of %c = %d",c,c);
return 0;
}
Output
Enter a character: G
ASCII value of G = 71
