Variables in C Language.

Variables in C Language. **Introduction** Variables are the fundamental building blocks of any programming language, including C. They serve as placeholders for storing data that a program manipulates, processes, and displays. Understanding how variables work in C is crucial for every programmer's journey. In this blog post, we'll take a comprehensive look at variables in C programming, covering their types, declaration, initialization, and scope. **Types of Variables in C** C supports several data types to cater to different kinds of data, such as integers, floating-point numbers, characters, and more. Here are some of the primary variable types in C: 1. int:  Used for storing integer values. 2. float:  Used for storing floating-point (decimal) values. 3. char : Used for storing single characters. 4. double : Used for storing double-precision floating-point values. 5. short  and long : Modifiers used with int to create different sizes of integers. 6. unsigned : Used with...
