Question

Write a C++ program to read N numbers. Find sum, product, and average of N numbers

Answer 1

// here is code in c++

// headers

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int n,num;

double sum=0, avg;

long long int prod=1;

cout<<"Enter value of N:";

// read value of N

cin>>n;

cout<<"enter "<<n<<" numbers:";

// read the N numbers

for(int x=0;x<n-1)

{

cin>> num;

// calculate sum of all

sum=sum+num;

calculate product of all

prod=prod*num;

}

// print sum

cout<<"sum of all "<<n<<" numbers is: "<<sum<<endl;

// print product

cout<<"product of all numbers is : "<<prod<<endl;

print average

cout<<"average of all "<<n<<" numbers is: "<<sum/n<<endl;

return 0;

}

Step-by-step explanation:

Read the value of n from user.Then ask user to enter n numbers. Then calculate sum of all entered number and their product.After this calculate the average of entered number by dividing sum with n.Print sum, product and average of n numbers.

Output:

enter value of N:6

enter 6 numbers:1 2 3 4 5 6

sum of all 6 numbers is: 15

product of all numbers is : 120

average of all 6 numbers is: 2.5
