Basics Of C++ - Get started on programming with C++

This tutorial will teach you how to run the Horner's algorithm, for number conversion. It converts numbers from a specified numeric system into decimal, without using powers, which makes the whole process faster. The tutorial won't explain why these arithmetic calculations do so, but just how to run them.

Most of beginners define arrays of limited size such as:

int array[100]; // array that can accomodate 100 integer values

These are ok, but your requirement may be different, and you want your application to determines the size of array at runtime, so if your requirement is to use 10 elements only, that means 90 are unused but memory is still allocated for them while application is running. On other hand your application requires 110 elements to be saved, the last 10 will be unallocated spaces if array size is 100, and access to unallocated memory address may result in applciation crash and/or system level damage.

A small book for those beginners in C++ or even in programming who didn’t understand C++ data types. This is meant to be a patch to other books, that cover the basics of C++. Data types can be a little tricky sometimes, and difficult to understand, this book explains how data types work, and also shows you how to use them by giving examples.
