What is the average value of an array in C++?

How do I calculate the average value of an array in C++?

To calculate the average value of an array in C++, you need to sum all the elements and then divide by the number of elements.

Can you show me a code example?

Sure! Here's a simple example:

#include <iostream>
using namespace std;

int main() {
    int arr[] = {10, 20, 30, 40, 50};
    int sum = 0;
    int n = sizeof(arr) / sizeof(arr[0]);

    for(int i = 0; i < n; i++) {
        sum += arr[i];
    }

    double average = static_cast<double>(sum) / n;
    cout << "Average: " << average << endl;
    return 0;
}

What if the array has a different size?

The code will still work! Just change the elements in the array, and the size will automatically adjust based on the number of elements you provide.

Can I use vectors instead of arrays?

Absolutely! You can use vectors in C++ for dynamic sizing. Just include the <vector> header and use std::vector<int> arr = {10, 20, 30};.
