Write a program which asks the user to enter n numbers. the program will print out their average. try your program with the following numbers: 20.5, 19.7, 21.3, 18.6 and 22.1

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variables

int n;

double average,sum=0,x;

cout<<"enter the Value of N:";

// read the value of N

cin>>n;

cout<<"enter "<<n<<" Numbers:";

// read n Numbers

for(int a=0;a<n;a++)

{

   cin>>x;

   // calculate total sum of all numbers

   sum=sum+x;

}

// calculate average

average=sum/n;

// print average

cout<<"average of "<<n<<" Numbers is: "<<average<<endl;

return 0;

}

Explanation:

Read the total number from user i.e "n".Then read "n" numbers from user with for loop and sum them all.Find there average by dividing the sum with n.And print the average.

Output:

enter the Value of N:5

enter 5 Numbers:20.5 19.7 21.3 18.6 22.1

average of 5 Numbers is: 20.44
