## Free Programming Courses at SoftUni

SoftUni organizes free programming lessons for beginners all across Bulgaria. You can choose between on-site and online training. The purpose is to give a chance to everyone who is interested in programming and technologies to try programming, and check if they are interested and if they would get seriously involved in software development. You can sign up for the free course in programming basics using the SoftUni application page: http://softuni.bg/apply.

The free courses at SoftUni have the purpose to introduce you to basic programming constructions in the software development world, that you can use at any programming language. These include working with data, variables and expressions, using conditional statements, constructing loops, defining and calling methods and other approaches for building programming logic.

This programming book accompanies the free programming lessons for beginners in SoftUni and serves as an additional teaching aid to help the learning process.

## About the Automated Judge System

The SoftUni Judge system (http://judge.softuni.bg) is an automated Internet system for verifying the solutions of programming exercises via series of tests. The submission and verification happens in real time: you submit the solution and within seconds you receive an answer whether it is correct. Each successfully taken test gives you the points it gains. For a correct solution you get all the points for the particular task. For partially correct solution you get part of the points for the task. For a completely wrong solution you get 0 points.

All tasks from the current book are available for testing in SoftUni judge and we strongly recommend to test them after you solve them to be sure you don't miss anything and that your solution works correctly according to the task requirements.

Keep in mind some specifics about SoftUni judge:

• For each task the judge system keeps the best score you had. Therefore if you upload a solution with wrong code or lower score compared to the previous one, the system won't take away your points.
• The output of your program is compared by the system to a strictly expected result. Every unnecessary symbol, missing comma or interval may lead to 0 points on a particular test. The output that the judge expects is described in the requirements of every task and nothing else should be added.
• Example: If the output requires to print a number (ex. 25), do not display any descriptive messаges such as The result is: 25, just print as it is required, i.e. only the number.

The SoftUni judge system is available any time via its website: https://judge.softuni.bg.
