* vs & (pointer, reference) in C

C programming language is a strong statically typed language. This means that we are responsible for the declaration of variable type, dynamic memory allocation and free of such memory space after it has been used explicitly. Pointer and reference are very important concepts in C.

In this article, we will look at the concept of pointer and reference in C.

Tic tac toe game in Python

In this article, we have presented how to develop the classic Tic Tac Toe game project in Python Programming Language. This will be a strong addition to Software Developer Portfolio.

What is Tic-Tac-Toe ?

Tic tac toe, also known as noughts and crosses or Xs and Os, is a simple strategy game for two players. It is played on a 3x3 grid, and each player takes turns placing their symbol (either an X or an O) on an empty space on the grid. The first player to get three of their symbols in a row (ho...

Static and Global Variables in Recursion

What is Recursion?
A function that calls itself is called a recursive function.

In this article, we are going to see how recursion uses Static and Global Variables with the help of examples.
