Basics

-

I. Introduction

-

- A C++ program generally consists of preprocessor directives and the main function.
-
- A preprocessor directive tells the C++ preprocessor what to do before compiling. You can use this to include files, create macros, and determine compiling based on conditions. For example, include a file using #include This will include the iostream file from the C++ standard library.
-
- The main function looks like: - 

int main() {
-		std::cout << "Hello world" << '\n';
-		return 0;
-	}
- The int main() { is the declaration of the main function denoting it returns type int. return 0; is the return statement for the function. It is returning the integer 0. This tells the operating system, OK Quit the program safely. -

II. Variables

-

- A variable lets you allocate some memory in the computer and use it to store values. You can also recall the values for later. Variables contain a memory address and an identifier. An identifier can be *almost* anything you wish it to be.
-
- Variables naming rules: -

- - All variables have denoted types and they refer to what kind of variable it is. All variables also have a bit size and this denotes the range of values that can be stored.
-
- Variable types: - -
- Variables are always declared before they are initialized. This means you must determine the type and the identifier before you store any values into it.
-
- 
int main() {
-		int a; // Declaration
-		a = 1; // Initialization
-		int b = 2; // Declaration then initialization
-	}

-
- Constant types are variables identified by const in their type definition. These are not allowed to be modified after they are declared and must be initialized at declaration. -
