This document discusses variables in C programming. It explains that variables are names that refer to memory locations where values can be stored and changed during program execution. It provides the syntax for declaring variables using different data types like int, float, double, and char. Rules for variable names are also outlined, such as starting with a letter or underscore and avoiding reserved words.
A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.
This C tutorial covers every topic in C with the programming exercises. This is the most extensive tutorial on C you will get your hands on. I hope you will love the presentation. All the best. Happy learning.
