In this tutorial we tackle the idea file IO using basic input output functions. We also learn about the basic concept of a stream, learn the difference between binary mode and text mode, and Chili even sneaks in a dank Cypress Hill reference.
Topics Covered
- Opening a file for reading with
std::ifstream - Reading with
get()and monitoring the steam state withgood() - Detecting the EOF (End of File) as well as errors in reading and file opening
- Writing to files with
std::ofstream - The working directory of the application (where it looks for files)
- The difference between binary mode and text mode
- Writing and reading blocks of bytes with
write()andread()

Homework
Write a console application where the user can enter a fixed number of data pairs consisting of name:value in the form of c-string:unsigned int. Store the entries in memory, and allow the user to print out a text chart of the entry data on demand. Also allow the user to save the entries to a file and load a file of entries into memory. You may not use any library functions beyond what is already being used in the Intermediate series.
