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 programming, dynamic memory allocation allows us to allocate memory at runtime. Two commonly used functions for this purpose are malloc and calloc. While they may seem similar, there are important differences between the two. This article explores these differences with examples.
In C programming, controlling the flow of the program is the key to unleashing the true potential of your code. In this article, we will look into the loops and control statements which are fundamental constructs and shape the flow of execution in your programs.
In C Programming, operators are symbols or keywords used to perform operations on values and variables. These are fundamental to performing various operations in C programming and are essential for building complex algorithms and programs. We can use operators to perform a wide range of tasks, including arithmetic calculations, logical operations, and comparisons.
A structure is combination of different data types. Lets take the example of a book, if we cant to declare a book we will be thinking about the name, title, authors and publisher of the book and publishing year. So to declare a book we need to have some complex data type which can deal with more than one data types.
A pointer can be declared to point to another pointer which points to a variable. Here, the first pointer contains the address of the second pointer. The second pointer points to an actual memory location where the data is stored, i.e. a variable. That’s the reason why we also call such pointers as double pointers.
This is a C program to demonstrate cache mechanism by simulating a cache in C. The source code can run in any C Compiler with minor modifications if required. It can run on real memory traces as input to your cache simulator. We have implemented two cache replacement policies i.e. least recently used (LRU) and First-in first-out (FIFO) replacement policies.
Generally, the following two statements about char[] and char * in C are considered confusing and understanding the difference between them is important. The first statement puts the literal string “mycplus” in read-only memory and copies the string to newly allocated memory on the stack. The second statement is known as static string allocation and definition.
In the C Programming Language, the #ifndef directive checks if the given token has been #defined earlier in the C code. If the token has not been defined earlier then it includes the code between #ifndef and #else. If no #else is present then code between ##ifndef and #endif is included.
C Standard Library provides two different methods to generate random numbers. They are: rand() and srand().
This article is about a collection of common Computer Science algorithms which may be used in C projects. The C Programming Language has a much smaller Standard Library as compared to other more modern programming languages such as Java or Python. The library provides a basic set of mathematical functions, string manipulation, type conversions, and file and console-based I/O.
In C Programming, ternary operator allows executing different code depending on the value of a condition. The returned value is the result of the expression when the code is executed. The main advantage of using ternary operator is to reduce the number of lines of code and improve the performance of application. In C, the real utility of ternary operator is that it is an expression instead of a statement i.e. you can have it on the right-hand side (RHS) of a statement. So you can write certain code statements more concisely.
Every C programmer starts with the same five lines. This guide explains each one, then shows you how to compile, run and extend your first C program.
