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.
This is a small C language program that can read a text file. The program is given file name as command parameter and it reads the file line by line. The program will prints out number of characters and words in each line.
C Programming File Handling Source Code
A pointer is a variable that represents the location of a data item, such as a variable or an array element. Pointers are used frequently in C, as they have a number of useful applications. For example, pointers can be used to pass information back and forth between a function and its reference point. Pointers provide a way to return multiple data items from a function via function arguments to
be specified as arguments to a given function.
Arrays C Programming Memory Allocation
In C Programming, an array can be defined as number of memory locations, each of which can store the same data type and which can be referenced through the same variable name. Arrays can be of two types i.e. One Dimensional Array (such as lists) and Multidimensional Arrays (such as tables or matrices).
Arrays C Programming
This tutorial covers many topics in VGA programming in the C programming language. Tutorial assumes that the programmers have a comprehensive understanding of C and should also have a familiarity with DOS and BIOS function calls and interrupts. Knowledge of trigonometry and geometry would also be helpful.
