C programming supports two special preprocessor directive for string operations. Stringize (#) and token pasting (##) are C preprocessor string manipulation operators.
In previous article we learned about basic and conditional preprocessor directives in C language. In this article we will move further and learn string manipulation preprocessor operators.

A C preprocessor is a statement substitution (text substitution) in C programming language. It instructs the C compiler to do some specific (required) pre-processing before the compilation process.
When we compile a C program, C preprocessor processes the statements which are associated with it and expand them to make the code for further compilation.

Pointer is the most important and powerful tool in C language. Pointer resolves many complicated problems easily but if you don’t have the sufficient knowledge of pointers, you will face problems like segmentation fault etc.
In this article, I will describe five common pointer mistakes in C programming which generally occurs.

Write a C program to implement queue data structure using linked list. In this post I will explain queue implementation using linked list in C language.
In previous post, I explained about queue implementation using array. Here, I will explain how to implement a basic queue using linked list in C programming. Along with I will explain how to perform enqueue and dequeue operations on Queue in C language.

In this article we will talk about
typedef in C language. I will explain what is
typedef, its use and how to use it in C language.

Unions in C are user defined data type similar to structures. Union allows to define multiple members of different type at single location. In this article I will explain what is union, need of union, how to declare, define and access unions in C programming language.
We use unions to define a new data type, similar to structures in C. Its definition, use and access are almost similar to structures. If I say its similar to structure, then you may think why in the world do we need it then. Hence, let us first explore the real world need of a union type.

Structures in C, is an advance and most popular topic in C language. It facilitates you to design your custom data type. In this tutorial, we will learn about structures in C its need, how to declare, define and access structures.

Dynamic memory allocation refers to the process of manual memory management (allocation and deallocation). Dynamic memory allocation in C is performed via a group of built-in functions
free(). Some text also refer Dynamic memory allocation as Runtime memory allocation.

Bitwise operators are used to manipulate data at its lowest level (bit level). Data in memory (RAM) is organized as a sequence of bytes. Each byte is a group of eight consecutive bits. We use bitwise operators whenever we need to manipulate bits directly. In this post I will show you some cool bitwise operator hacks and tricks. These hacks will boost your programming skill.

Data at the centric level is most crucial part of every program that you have written. All programs contain memory allocation, deallocation and data manipulation. In this article, I am going to discuss about memory allocation and different ways to allocate memory in C.
