Course Introduction
Programs for practice
In the C++ program below,we ask the user to enter the number size (say n), then ask to enter n numbers to calculate and display the arithmetic mean of all the numbers:
Source Code: Calculate Arithmetic Mean in C++
/* C++ Program - Calculate Arithmetic Mean using Array */
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int n, i, arr[50], sum=0;
cout<<"How many number you want to enter ?\n";
cin>>n;
cout<<"Enter "<<n<<" Numbers :";
for(i=0; i<n; i++)
{
cin>>arr[i];
sum=sum+arr[i];
}
int armean=sum/n;
cout<<"Arithmetic Mean = "<<armean;
getch();
}
Output
How many number you want to enter ?
