Working with Text Files: Basics

This lecture covers the fundamentals of working with text files in C programming. It starts by explaining the purpose of text files and the two main types: text files and binary files. The instructor demonstrates how to open, read from, write to, and close text files using functions like fopen, fclose, fgetc, fgets, fprintf, and more. Examples are provided to illustrate concepts such as creating new files, counting lines, and finding specific text in a file. The lecture also discusses moving the file position indicator, checking for end-of-file and error indicators, and the importance of using files to store and reuse data efficiently.
