In this C++ tutorial, you shall learn how to write a program to find the average of elements in the given integer array.
C++ Find Average of Elements in Integer Array
To find the average of elements in an integer array, loop through the elements of this array using a For Loop or While Loop, accumulate the sum in a variable, and then divide the sum with the number of elements in array.

Examples
1. Find average of integers in the array {2, 4, 6, 8}
In the following example, we take an integer array initialized with some elements, and find the average of the elements of this array.
main.cpp
#include <iostream> using namespace std; int main() { int x[] = {2, 4, 6, 8}; //integer array int len = sizeof(x) / sizeof(x[0]); //get array length int sum = 0; //initialize sum with 0 float avg = 0; //initialize average with 0 for (int i = 0; i < len; i++) { sum += x[i]; //accumulate sum } avg = sum / len; cout << "Average : " << avg << endl; }
Output
Average : 5 Program ended with exit code: 0
Conclusion
In this C++ Tutorial, we learned how to find the average of elements of an integer array, with the help of example C++ programs.
