S7:EP6 File Handling and Records in Programming

This episode outlines fundamental concepts in file handling and data structures within programming. They emphasize the three essential steps for interacting with files: opening, reading/writing, and closing. The text details how records are used to store data, particularly in the context of databases and 2D arrays which can emulate database tables. It also explains text files as a method for storing collections of records, often in a CSV (comma-separated values) format where data fields are separated by commas and each record occupies a new line. Different file opening modes (write, append, read) are described, alongside practical examples and algorithms for reading from and writing to text files.
