Program 1 : 

// C program to compute sum of digits in
// number.
#include <stdio.h>

/* Function to get sum of digits */
int getSum(int n)

    int sum = 0;
    while (n != 0)
        sum = sum + n % 10;
        n = n / 10;
    
    return sum;

// Driver code
int main()

    int n = 687;
    printf(" 0 ", getSum(n));
    return 0;

 

Program 2: 

#include<stdio.h>
#include<conio.h>
void main()

int n,i;
float avg[5],s1[5],s2[5],s3[5],sum[5];
clrscr();
for(i=0;i<5;i++)

printf(" Enter marks of students 0 in 3 subjects:",i+1);
scanf("000",&s1[i],&s2[i],&s3[i]);

for(i=0;i<5;i++)

sum[i]=s1[i]+s2[i]+s3[i];
avg[i]=sum[i]/3;

for(i=0;i<5;i++)
printf(" Student 0's marks: Total : %.2f Average : %.2f",i+1,sum[i],avg[i]);
getch();
