How to find the average of int array in C++

Answer 1

#include <iostream>
using namespace std;

int main()
{
	int arr[] = { 1, 2, 3, 4, 5, 6 };
	float sum = 0;
	int arr_size = sizeof(arr) / sizeof(arr[0]);

	for (int i = 0; i < arr_size; i++)
			sum += arr[i];

	cout << "average = " << sum / arr_size << endl;
	
	return 0;
}

/*
run: 

average = 3.5

*/
