The size of a class can be changed simply by playing with the order of its members' declaration: struct A { bool a; int b; bool c; }; /*sizeof (A) == 12*/ On my machine, sizeof (A) equals 12. This result might seem surprising because the total size of A's members is only 6...

Polymorphism is in short the ability to call different functions by just using one type of function call. It is a lot useful since it can group classes and their functions together. It is the most important part of Object-Oriented Programming. Polymorphism is the core of object-oriented programming...

Introduction Variables are seen as memory cells that can be accessed using their identifiers. This way we did not have to care about the physical location of our data within memory, we simply used its identifier whenever we wanted to refer to our variable. The memory of your computer can be...

Introduction To Binary Trees A binary tree is made of nodes, where each node contains a "left" pointer, a "right" pointer, and a data element. The "root" pointer points to the topmost node in the tree. The left and right pointers recursively point to smaller "subtrees" on either side. A null...

I posted a little about this in Sudoku Solving Program Using 'C' so that people could take a look at the solve part of the algorithm if they wanted. I was mid-development and this wasn't the part that was actually to change much except for a removal tweak of a magic number here and there. Since...
