C++ Program to Calculate Arithmetic Mean

Posted by AbundantCode

Problem

Write a program in C++ to calculate arithmetic mean for the numbers entered by the user.

Solution

We have a formula to find the arithmetic mean if there are n sets of numbers:

am = (n1+n2+n3+...+nn)/n

The letters am stand for arithmetic mean, whereas n1, n2, n3, and nn stand for first, second, third, and fourth numbers, respectively.

Here’s a sample code snippet demonstrating how you can find the arithmetic mean in C++.

#include<iostream>
using namespace std;
int main()
{
    int n, i;
    float arr[50], sum=0, armean;
    cout<<"Enter the Limit";
    cin>>n;
    cout<<"\nEnter the Number: ";
    for(i=0; i<n; i++)
    {
        cin>>arr[i];
        sum = sum+arr[i];
    }
    armean = sum/n;
    cout<<"\nArithmetic Mean = "<<armean;
    cout<<endl;
    return 0;
}

Output
