1. Getting Started

In this section, we dive into learning the structure of a default C++ program

Why to Learn C++

Entry Point of a Program

Standard Library and Files

Preprocessor Directives

The First Program

2. Variables and Data Types

In this section, we will learn how to manipulate different variables.

Introduction to Variables

Numerical Data Types

Introduction to String

Introduction to Arrays

Keywords sizeof(), auto and typedef

Working with the Array

3. Introduction to Operators

In this section, we will learn how to equate and compare variables, and use mathematical and bitwise operators.

Simple Operators

Logical Operators

Compound Assignment Operator

Bitwise Shift Operators

Practicing Math Basics

4. Introduction to Program Flow

In this section, we will learn how to control the flow of our programs.

If...else Statement

Ternary Operator

Switch Statement

Do...while Loop

Fibonacci Number with Loops

5. Introduction to Functions

In this section, we will explore the concept of functions, and how to create and call them.

What are Functions?

Type of Functions

Return Statement in Functions

Functions With Arguments

Simple Function

Simple Operators

The assignment operator (=) is used in programming to assign a value to a variable. The syntax looks as follows:

main.cpp

It works exactly the same with the string data type:

main.cpp

The equality (==) and inequality (!=) operators are used to numerically compare 2 variables:

main.cpp

Why 1 and 0? This is an alternative approach for utilizing the boolean data type. When the expression var == 9 is true, it is represented as 1, and it means that var is indeed equal to the number 9. Conversely, when the expression var == -9 is false, it is represented as 0, indicating that var is not equal to the number -9.

The inequality (!=) operator is doing exactly the opposite:

main.cpp

Everything was clear?
