# Chapter 1 Definitions

Basic definitions are covered in this chapter.

**Naming conventions:**

**Camel Case:** firstName - first letter of first word is lower case, and first letter of all other words should be Upper case. **Pascal Case:** FirstName - first letter of every word should be upper case. **Hungarian Notation:** append type to the identifier like, strFirstName str is type here.

For local variables use Camel case like int number; For constants use Pascal Case like const int MyValue = 5;

**Note: Since I use all the commands before I udpate in this site, some of the datatypes are given with first letter as uppercase. But always use small letters for datatypes.**
