finding average of elements in array using struct in C?

Code to find average of elements in array using struct in C

#include <stdio.h>

struct Array {
    int arr[5];
};

float findAverage(struct Array a) {
    int sum = 0;
    for (int i = 0; i < 5; i++) {
        sum += a.arr[i];
    }
    return (float)sum / 5;
}

int main() {
    struct Array myArray = {{1, 2, 3, 4, 5}};
    float avg = findAverage(myArray);
    printf("Average of array elements: %.2f", avg);
    return 0;
}

Explanation:

• We define a struct named Array with an array arr of size 5 to hold the elements.
• The function findAverage takes a struct of type Array as an argument and calculates the average of the elements in the array.
• Inside the findAverage function, we initialize a variable sum to 0 to store the sum of the elements in the array.
• We use a for loop to iterate through the array and calculate the sum of its elements.
• We return the average of the elements by dividing the sum by the total number of elements in the array, casting the result to a float to obtain a decimal value.
• In the main function, we create an instance of Array named myArray and initialize it with values {1, 2, 3, 4, 5}.
• We then call the findAverage function, passing myArray as an argument, and store the result in the variable avg.
• Finally, we print the average of the array elements using printf.
