C Program to Calculate Average of Array Elements
In this program, the user is ask to enter 5 integer elements that will save in array arr. Then we calculate the sum and average of these number display it on console.
Source Code
#include<stdio.h>
int main()
{
int arr[5], i, sum = 0;
float avg;
printf("Enter 5 array students\n");
/* Input marks of 10 students */
for(i=0; i<5; i++)
scanf("%d", &arr[i]);
/* Logic to calculate sum and average*/
for(i=0; i<5; i++)
{
sum = sum + arr[i];
}
avg = sum / 5;
/* Print sum */
printf("\nSum = %d", sum);
printf("\nAverage = %0.2f", avg);
return 0;
}Output
Enter 5 array students
4 2 5 8 6
Sum = 25
Average = 5.00
