In this c program, you will learn how to calculate average of numbers (entered by the user) using array in c.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
#include<stdio.h> int main() { int n, i; float num[100], sum =0.0, average; printf("Enter the numbers of elements : "); scanf("%d",&n); while(n >100|| n <=0) { printf("Error! number should in the range of (1 to 100).\n"); printf("Enter the number again : "); scanf("%d",&n); } for(i =0; i < n;++i) { printf("%d. Enter number : ", i+1); scanf("%f",&num[i]); sum += num[i]; } average = sum / n; printf("Average of the numbers is = %.2f", average); return 0; } |
When you run above program, the output will be following:
|
1 2 3 4 5 6 |
Enter the numbers of elements : 4 1. Enter number : 2 2. Enter number : 8 3. Enter number : 9 4. Enter number : 4 Average of the numbers is = 5.75 |
