Syllabus

Introduction

Motivational introduction to my course about C++ and info about how to download 100+ exercises regarding C++.

Basics

You will learn what a programming language like C++/IDE and a compiler is. What is C++?

If you have a problem compiling your C++ project than look here to find a solution. Some IDE's might be a bit different. You might have also made a few mistakes. Let's try to solve the problem.

what are:
- comments
- libraries like iostream
- std namespace
- how to send something to the output (cout)

We are exploring the concept of "variable", "variable type", "declaration", "definition". Exploring naming rules of variables and notations.

We learn basics types of variables in the c++ language like:
- int, float, double, string, char, bool
We learn about address of variable, how to combine string, what are unsigned variables, what are constant variables and when to use them.

We learn how to download data using cin>> and we write a simple program that loads first name and surname, then it prints out that values in the console output.
