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.
Why MYCPLUS Trusted by C programmers since 2004 — every tutorial includes working source code you can compile, run and learn from immediately.
In C, an array can be initialized using aggregates, which are a collection of values enclosed in braces ({}) and separated by commas. Another way to initialize array by using a loop which allows you to set the initial values of an array using a more flexible and dynamic approach. The basic idea is to use a loop to assign values to each element of the array based on some condition or calculation.
This is a Borland C/C++ compiler Interface using the graphics.h library. This program uses many functions of graphics.h library provided by C Language. These functions include line(), setcolor(), outtextxy() etc.
This is a Game program written in C++. The objective of the game is to get to your proper plane on
This C program is a simple banking system designed for novice programmers. The program uses graphics.h for graphical user interface elements, such as windows and buttons, and provides basic banking functionalities like creating a new account, listing all accounts, and handling account transactions. The program starts with an introduction, displaying the name of the bank using basic graphics functions.
This C program compares two distinct arrays and if the arrays are same then content results in FALSE. The behavior of comparison is explained when we note that the comparison is a comparison of addresses, not contents.
This source code is from Thinking in C++, 2nd Edition, Volume 2, by Bruce Eckel & Chuck Allison. You can use Borland, G++ (For version 3 and above only), Microsoft (For C++ with .NET only) to compile and build this source code. Writing perfect software may be a daunting task for developers, but a few defensive techniques which are routinely applied can go a long way toward narrowing the gap between code and ideal. Defensive programming practices are often used where high availability of the application is required, safety if utmost concern, or security is needed for application to work.
This C++ program shows how to use enumerated type . The enum is a compound data type and works in
File input and output operations are essential to many C++ programs, but they can be cumbersome and difficult to manage. Fortunately, C++ provides a powerful mechanism for handling these operations: streams. Streams are a high-level abstraction that simplifies the process of reading and writing to files.
This C program demonstrates basic functionalities for handling integer arrays. It allows users to input integers into an array, prints the array, and performs linear searches based on user input until the user enters 0 to terminate.
The Smith-Waterman algorithm is used for comparing two sequences, typically biological sequences like DNA, RNA, or proteins. It finds the local similarities between the sequences, identifying regions where they match or align.
This C code multiplies two 2×2 matrices. It prompts the user to input values for both matrices, displays the input matrices, performs matrix multiplication using nested loops, and then prints the resulting matrix. The code adheres to modern C standards, using printf and scanf for I/O and avoiding outdated functions for better readability and compatibility.
This C program uses enumerated types to display days of week. The enumerated type is then declared as a different name using typedef keyword i.e. enum days to typedef enum days days. The function prints for each day of the week, today, yesterday, and tomorrow, both as a string and as a number.
