return

A function which will find the average of all elements of an array of integers.

float average(int array[], int dimension)

{

    //declare local variable avg of float type

    float avg;

    //declare integer type variable sum

    int sum=0;

    //for loop run until dimension

    for(int i=0; i<dimension; i++)

    {

        //compute sum

        sum=sum+array[i];

    }

    //compute average

    avg=sum/dimension;

    //retrun avg

    return avg;

}

The following program is written in the C++ programming language.

Program:

//included header file

#include <iostream>

//included namespace

using namespace std;

//function which will find the average

float average(int array[], int dimension)

{

    //declare local variable avg of float type

    float avg;

    //declare integer type variable sum

    int sum=0;

    //for loop run until dimension

    for(int i=0; i<dimension; i++)

    {

        //compute sum

        sum=sum+array[i];

    }

    //compute average

    avg=sum/dimension;

    //retrun avg

    return avg;

}

//main function

int main ()

{

    //declared array with given elements

    int array[]={5, 7, 3, 5, 6, 4};

    //declared flaot type variable avg

    float avg;

    //declared variable dimension of integer type

    int dimension=6;

    //calling function average

    avg=average(array, dimension);

    //print average of all elements of an array of integers

    cout<<"The average of all elements of an array of integers is:"<<avg;

    return 0;
