Introduction

Welcome to the last part of the programming basics series! In this series we’ll cover what exceptions are and how you deal with them.

If you’ve made all the examples, that are featured throughout the series, you might have encountered something like this:

This particular runtime error is caused by a wrong user input. It’s not caused by faulty code. Errors like this usually crash your application and a user has to restart it, in order to continue using it. In this part we’ll cover how to deal with such errors.

Programming Basics 5 – Control flow

Introduction

This part will teach you, how to compare values and control the flow of your program. It will also teach you, how to repeat a part of your program for a defined number of times, which is very useful for tasks like processing user input or printing out data.

If you want to store multiple inputs of the same type, for example numbers for a calculator, you’ll have to create different variables for each input, right?

In this part you’ll learn, how to store multiple values into one variable (sort of).
