Question

I am in C++ programming, I need help with this assignments. The answer in this assignments when I look for it it doesn't work in my visual studios. Can you please help me? I hardly have C in the class, if I fail I will fail the whole class and repeat this class again.  

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

Source code:

#include <iostream>
#include <fstream>
using namespace std;

int main()
{
   ifstream fs("Random.txt");
   int num,count=0;
   double sum=0.0,avg=0.0;
   while(fs>>num)
   {
       ++count;
       sum=sum+num;
   }
   avg=sum/count;
   cout<<"Number of numbers in the file:"<<count<<endl;
   cout<<"The sum of all numbers in the file:"<<sum<<endl;
   cout<<"The average of all numbers in the file:"<<avg<<endl;
}

Random.txt:

1 10 9 8 7 6 5 4 3 2 1

1 #include <iostream> 2 #include <fstream> 3 using namespace std; 4 5 int main() 6 { 7 ifstream fs("Random. txt"); 8 int num, count=0; 9 double sum=0.0, avg=0.0; 10 while(fs>>num) 11 { 12 ++count; 13 sum=sum+num; 14 15 } 16 17 avg=sum/count; cout<<"Number of numbers in the file:"<<count<<endl; cout<<"The sum of all numbers in the file:"<<sum<<endl; cout<<"The average of all numbers in the file:"<<avg<<endl; 18 19}
Sample input and output:

(base) rgukti@rgukt-TravelMate-P243-M:-/Desktop$ ./a.out Number of numbers in the file: 10 The sum of all numbers in the file:55 The average of all numbers in the file:5.5 (base) rgukt1@rgukt-TravelMate-P243-M :-/Desktops |
