Introduction
Definition: Pointer is a variable which stores address of another variable.
To understand this definition properly, let us separate it into two statements:
1. Pointer is a variable.
2. It stores address of another variable.
Consider the first statement, it means that a...

Many of us know that both C and C++ do padding when allocating memory for structure.
But only few know that why the complier does it. In short, for the efficient access of the memory for OS, padding is required.
In long words, the instruction can be fetched/written one machine word at a time....

Mostly people are using this algorithm to compute matrix multiplication:
#define n 1000

There are times when you write a small or a big code and when you execute it you get a very small and precise output 'Segmentation fault'. In a small piece of code its still easy to debug the reason for this but as the code size grows it becomes very difficult to debug. Here in this article, I am...

The code below swaps two nodes in the linked list. The swap operation can be helpful in sorting a linked list and so its very important how to swap the nodes of linked list.
Swapping in normal arrays is swap of the data but in linked list its the pointers change and so there is just change in...

Listed here are few common complex operations of single linked list that is to be needed by certain applications. These operations should be done in single traversal for improved performance.
Here are few of them and their solutions..
1. Reverse the list.
2. Find n-th node from tail end....

In a language like 'C', the programmer has almost complete control over memory operations but this brings in a problem that many of you might have faced : Memory errors. Although GDB can be used in many areas of these kind of problems but there are sometimes when programmer doesn't want to put too...

In this article I'm going to show you how to change value of variable during run time. There are many tools around how to do this easily, but I will focus on the way doing it programatically, specifically using C language.
Tools I will use: Cheat Engine 6.0
Here is a simple code for login, I...

Typecasting is simply a mechanism by which we can change the data type of a variable, no matter how it was originally defined. When a variable is typecasted into a different type, the compiler basically treats the variable as of the new data type.
Example
Lets go for a very simple example :

This article assumes that readers are aware of what pointers are and how they are used in 'C'. As a quick overview, A pointer is a special variable which holds the address of a variable of same type. For example :
Lets say there is a variable 'int a=10' so,a pointer to variable 'a' can be...

Most of the newbie programmers are fascinated by the term 'hacking' or 'cracking'(to be precise). Generally, they see some weirdly written code (that may visually seem like a painting to any new programmer) and start dreaming of the developer who has written the code as god of programming or...
