How do you get a file in C++?

Question

So the teacher has posed this assignment:

You have been hired by the United Network Command for Law Enforcement, and you have been given files containing null cyphers yo

Answer 1

To do file operations, you need the correct include:

#include 

Then, in your main function, you can open a file stream:

ifstream inFile( "filename.txt", ios::in );

or, for output:

ofstream outFile( "filename.txt", ios::out );

You can then use inFile as you would use cin, and outFile as you would use cout. To close the file when you are done:

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