Brick Breaker Game in C and C++: Complete Source Code for the Terminal
A Breakout-style brick game in C and modern C++ for Windows, Linux and macOS terminals: full source, collisions, paddle aim, redraws and timing.
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.
Loops in C: for, while, do-while, break and continue (With Pitfalls and Exercises)
How for, while and do-while loops work in C, when to use each, how to leave nested loops, and the loop bugs compilers do not catch.
Unions in C: Memory Layout, Type Punning, Tagged Unions and std::variant
Unions in C explained with compiled examples: size and layout, type punning rules, tagged unions, and the C++ std::variant alternative.
malloc vs calloc in C: Differences, realloc, free and the Bugs That Matter
The difference between malloc and calloc in C, with measured costs, realloc and free, four heap bugs caught by sanitizers, and C++ new and delete.
TCP Client and Server in C: A Working Echo Example
Setting up a TCP connection takes six system calls. Using it correctly means handling a byte stream with no message boundaries and partial transfers.
Base64 Encoding and Decoding in C: Working Code and the Bugs to Avoid
The most copied base64 implementation in C has a heap over-read in its own example. Here is a correct one, checked against the RFC 4648 test vectors.
ICMP Ping in C: Raw Sockets, Permissions and Source Code
Before it sends a byte, a ping program has to get past the kernel. Portable C for Linux and macOS, the Winsock differences, and all four permission routes.
Ternary Operator in C (?:): Syntax, Examples and the Traps
Only one branch runs, but both decide the type — and that is where printf goes wrong. Tested C examples, plus the MAX macro trap.
Include Guards in C and C++: #ifndef, #define and #pragma once
A guard stops a header being pasted in twice. It does not stop it being defined twice. Tested examples, captured errors, and the pragma once myths.
if, else and else if in C: Conditional Statements Explained
The syntax takes a minute. The five ways it goes quietly wrong take longer — and every one of them compiles without an error.
Number Base Conversion in C — Binary, Octal, Decimal and Hex
Six conversion functions are really two algorithms. A tested base converter for every base from 2 to 36, and what the old menu program got wrong.
Input and Output in C — printf, scanf, and Safe I/O Patterns
scanf(“%s”) wrote 31 bytes into an 8-byte buffer. A guide to C I/O that shows the unsafe patterns failing rather than just naming them.
