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.

Print Pyramids and Diamonds Shapes in C Programming

So, here in this article I will demonstrate how you can print pyramids and diamonds using for loop and if condition using C Programming. Building a pyramid in c programming is quite easy, but you must have the understanding of how for loop works. With some slight modifications you can print different shapes as well.

graphics.h Reference

graphics: graphics.h Header File

This is the graphics.h header file which contains all the graphics functions and their implementations. It is quite nice to have a look at header files just to know more about functions and their parameters. Also it tells about different structures, enums defined in the file for specific purpose.

ICMP Ping - C Implementation

ICMP Ping Program in C

This sample illustrates how an ICMP ping app can be written using the SOCK_RAW socket type and IPPROTO_ICMP protocol. By creating a raw socket, the underlying layer does not change the protocol header so that when we submit the ICMP header nothing is changed so that the receiving end will see an ICMP packet. Additionally, we use the record route IP option to get a round trip path to the endpoint. Note that the size of the IP option header that records the route is limited to nine IP addresses.

C Program of Library Management System

This is a C program to implement Library Management System by which a librarian can operate a simple library. It uses Linked List, Stack and Pointers to implement different features of the library system. The program also uses struct data structure to add records in the library.

Datagram Operations using C

Datagram Operations using C

This application demonstrates the various datagram operations possible from NetBIOS. This includes sending and receiving both directed and group datagrams as well as broadcast datagrams.

Number Shuffling Game

C Program: Number Shuffling Game

This C program is a simple console-based implementation of a number-shuffling game. The game presents a grid of numbers, and the objective is to rearrange them in ascending order. The player can move the numbers by pressing the corresponding number keys, and the game tracks the number of moves taken to complete the puzzle.
