Read and write to a text file

[s123456]

read from data.txt file and write to results.txt in c drive.

here is the data.txt file (didn't press enter after number 5):
3
4
5


everything runs but the output repeats the number 5


Here are the numbers in the file:
3
4
5
5


Press any key to continue . . .

and in the results.txt file the only number outputted is the number 5

here is my code:

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

int main()
{
int num;
ifstream inFile;
ofstream outFile;


inFile.open("data.txt");


if (! inFile)
{
cout << "ERROR - File did not open!\n";
exit(1);
}

cout << "Here are the numbers in the file: \n";
while(!inFile.eof())
{
inFile >> num;
cout << num << '\n';
}


outFile.open("c:\\result.txt");

if(outFile.fail())
{
cout << "ERROR - File did not open!\n";
system("pause");
return 1; /// or return 1
}


cout << endl << endl;
outFile << num;


inFile.close();
outFile.close();


system("pause");
return 0;
}

changed to

while(inFile >> num)
{
cout << num << '\n';
}

works.

Thank you

@TheJJJunk

but now in the c drive the result.txt file doesn't include the
3
4
5



it just shows:
5



how do i make the 3 4 and 5 show?

[TheJJJunk]

Because you have outFile << num; and it's not in a loop, so it will only send the last value that was assigned to num. In this case 5.

You could assign 3, 4, and 5 to different variables? and then send them all back.

i can't specifically extract the numbers from data.txt
instead of creating variables
int a = 3;
int b = 4;
int c = 5;

creating a loop? but how? would i have to create a function?
