Question

How to find the Average Values of all the Array Elements in C#?

Answer 1

Minimum change solution:

float grades_average(float grades[7]){

int i;

float sum = 0;

float average = 0.0;

/* calculate the sum of grades using for loop*/

for(i = 0; i < 7; i++){

sum = sum + grades[i];

}

average = sum/7.f;

return average;

}

Change for(i = 0; i <= 7; i++){ to for(i = 0; i < 7; i++){. Valid indicies for grades are only 0-6. 7 is out of bounds.

Change sum = sum + grades[7]; to sum = sum + grades[i]; You need to check each element, not the (beyond) last one over and over.

Change average = sum/7; to average = sum/7.f; The .f ensures no integer division. That preserves the decimal during division.

I hope that helps!
