Help with input/output files
Hellow
I'm new to this forum, and I like it alot
It is just what I was looking for
I'm new at c++
for now, I'm at input/output files
and I have a problem
I have to write a program that reads some numbers (type double) from a file and outputs the avarage of it
"Read numbers from the input file in a loop, incrementing count and updating sum with each number read."
How do I have to read ALL files from the file
can someone tell me how the loop has to look like
here is my code so far
Code:
#include <fstream>
#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
ifstream fin;
int count = 0;
double val;
double sum = 0.0;
fin.open("numbers02.txt");
//HERE HAS TO COME THE LOOP
fin.close();
if (count > 0) {
cout << "Average of the " << count << " numbers in the file is " <<
(sum/count) << "\n";
}
else {
cout << "No numbers were found";
}
}
I'm new with files ... that's why I have problems :(
