C++ Developer - More File Input/Output (I/O)

The video tutorial covers reading and writing data from files using C++. It begins with setting up a project in Visual Studio, including placing input files in the correct directory. The tutorial then guides through writing code to read names and ages from separate files, combining them, and writing the output to a new file. Error handling is discussed, ensuring files are opened correctly. A challenge is presented to create a project that reads integers from a file, doubles them, and writes the results to another file.
