How to read a text file - C++

[BrucePerry]

This article is the second part of the article I made earlier on how to create a text file.

In this article you will be learning how to read the text file that we created, I will be teaching you how to put this code with the code we made but if you want to put it into a different project or source file and compile it separately that will work also.

Now lets start the code:
You should already have this in your source file:

#include<iostream>
#include<fstream>

using namespace std;

int main() {
 ofstream Myfile;
  Myfile.open ("test.txt");
  Myfile << "This is a test.";
  Myfile.close();

  return 0;
}

I did change myfile to Myfile with a capital for this tutorial.

1-> Made a space under "Myfile.close() ;" to make your code look cleaner and put in:

ifstream myfile;

ifstream provides an interface to read data from files as input streams.

2-> Under that open your file.

 myfile.open("test.txt");

3-> Now create a char, we are going to call our char "Output".

 char output[100];

4-> Now create an 'if' statement.

if (myfile.is_open()) {

}

5-> Inside the 'if' statement output the contents of your text file using the char.

 while (!myfile.eof()) {

    myfile >> output;
    cout<<output;
 }

6-> Now, under the if statement close your text file.

myfile.close();

Your code (If you did the first article also) should look like this:

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

int main() {
 ofstream Myfile;
  Myfile.open ("test.txt");
  Myfile << "Hello";
  Myfile.close();
 
 ifstream myfile;
 myfile.open("test.txt");
 char output[100];
 if (myfile.is_open()) {
 while (!myfile.eof()) {

    myfile >> output;
    cout<<output;
 }
}
myfile.close();
getchar();
getchar();
return 0;
}
