C Programming Tutorials — From Beginner Basics to Advanced Concepts

C is one of the most important programming languages ever created. Developed in the early 1970s, it remains the foundation of operating systems, embedded systems, compilers, and high-performance software used across the world today. Learning C gives you a deep understanding of how computers actually work — memory, pointers, data structures, and low-level system operations that higher-level languages hide from you.

At MYCPLUS we have been publishing C programming tutorials, source code examples, and practical guides since 2004. Whether you are writing your first Hello World program or working through complex data structure implementations, this section covers every stage of the C learning journey. You will find step-by-step tutorials, working source code you can compile and run immediately, and clear explanations of concepts that are often poorly explained elsewhere.

C is the language that powers Linux, Windows internals, embedded microcontrollers, game engines, and countless performance-critical applications. If you want to become a serious systems programmer, understand how memory works, or simply build a rock-solid foundation before moving to C++, Java or Python — start here.

What You’ll Learn:

  • Core C syntax — variables, data types, operators, control flow and functions explained from first principles
  • Pointers and memory management — heap allocation, pointer arithmetic, dynamic arrays and avoiding memory leaks
  • Data structures in C — arrays, linked lists, stacks, queues and trees implemented from scratch
  • File handling — reading and writing files, binary data and practical I/O operations in C
  • Algorithms in C — sorting, searching, recursion and graph traversal with working source code examples
  • Systems programming concepts — understanding how C interacts with the operating system, processes and memory

Why MYCPLUS Trusted by C programmers since 2004 — every tutorial includes working source code you can compile, run and learn from immediately.

graphics.h Reference

Graphics Library (graphics.h) Reference (part 2)

In the previous post I discussed few important functions mostly used to initialize and destroy the graphics mode in DOS environment. Today I will discuss graphics functions to draw different shapes and lines. So here we go by starting the line function which is most important function in creating any graphics.

graphics.h Reference

Graphics Library (graphics.h) Reference (part 1)

Graphics programming in C Language is discussed rarely. Today I will discuss some important functions of graphics.h in C programming Language and in the next coming article I will make a simple program to demonstrate the use of graphics functions. This is the part one of the article which discuses the important graphics function to create and destroy the graphics environment. In part two I will show you different graphics functions to draw shapes. And in last part I will add a sample program to demonstrate the use of graphics.h library. So let’s start with the description of important functions and their use.
