The file named Random.txt contains a long list of random numbers. Download the file to your system, then write a program that opens the file, reads all the numbers from the file, and calculates the following:

1. The number of numbers in the file
2. The sum of all the numbers in the file (a running total)
3. The average of all the numbers in the file

The program should display the number of numbers found in the file, the sum of the numbers, and the average of the numbers.

Answer 1

save those numbers in a text file "Random.txt" in the same folder where you will save this code

1 2 3 #include <iostream> #include <fstream> using namespace std; 4 5 int main() 6 { 7 8 9 = ifstream f; f.open("Random.txt"); int count 0; //to store count double sum = 0; //to store sum double var = 0; //to read from file while (f >> var) 10 11 12 13 14 { count++; sum += var; } 15 16 17 18 11 cout << "The number of numbers in the file is: << count; cout << "\nThe sum of all the numbers in the file: << sum; cout << "\nThe average of all the numbers in file is: " « sum / count; 19 20 ܒܐ

#include <iostream>

#include <fstream>

using namespace std;

int main()

{

    ifstream f;

    f.open("Random.txt");

    int count = 0;  //to store count

    double sum = 0; //to store sum

    double var = 0; //to read from file

    while (f >> var)

    {

        count++;

        sum += var;

    }

    cout << "The number of numbers in the file is: " << count;

    cout << "\nThe sum of all the numbers in the file: " << sum;

    cout << "\nThe average of all the numbers in file is: " << sum / count;

}
