There are different ways to compile a C program depending on your operating system and the compiler you use. Here are some common methods:           - If you are using Linux, you can use the **GNU Compiler Collection (GCC)**, which is a widely used and free C compiler. To use GCC, you need to install the build tools for your Linux distribution, which usually include GCC, make, G++, and other development libraries. You can install them using your package manager, such as apt or dnf². Then, you can use the command `gcc source_file.c -o program_name` to compile your source code file into an executable progra...

How to Use Macro and Preprocessor in C                                      M acro and Preprocessor in C Programming         Sure, I can tell you some details about macro and preprocessor in C. A macro is a fragment of code that is given a name. You can define a macro in C using the **#define** preprocessor directive. For example,           #define c 299792458 // speed of light` Here, when we use c in our program, it is replaced with 299792458 by the preprocessor¹. A preprocessor is a program that transforms your source code before it is compiled. It can perform tasks such as including header files, expanding macros, conditional compilation, etc. All preprocessor directives begin with a **#** symbol¹².

How to Start Learn C programming What is The C Programming Language? A Tutorial for Beginners This tutorial will give you a broad overview of basic concepts of the C programming language. We'll go over the history of the language, why and where it is used, the compilation process, and some very basic programming concepts that are common in most popular programming languages. This is not a complete guide to the language, but will rather give you a high level understanding of important C concepts and ideas as an absolute beginner to coding. Each language has its own syntax and specific ways of doing things, but the concepts covered here are common and applied to all programming languages. Having an understanding of how things work and these universal concepts can take you a long way in your coding journey. It makes learning a new technology easier in the long run. This tutorial takes heavy inspiration from the material covered in the first couple of weeks of the...
