About

The International Union Against Idleness (IUAI) announced a competition for an application that would motivate users. There are prizes involved. Since you like competing and know a little bit about programming, you asked your friend to prepare an interesting algorithm for a quick buck. Unfortunately, you weren't clear enough, and instead of a ready-made program, a friend prepared a flowchart of Honest Calculator. You will have to put some effort into assembling it.

Training project

This project allows you to practice and strengthen your coding skills, helping you get ready for more advanced tasks ahead.

What you'll learn

Once you choose a project, we'll provide you with a study plan that includes all the necessary topics from your course to get it built. Here’s what awaits you:

Collect data and check if users were attentive in school.

Perform the first calculations and check if users know how to handle zero.

Sometimes the numbers are so big that you have to store them. Implement this feature!

Now, it is time to tell users what the calculator thinks about equations.

Electricity costs money, the processor overheats, the memory fills up, so you have to watch what users want to store.

This project test was brutal. It was very strict with the output it would not accept an INT like 5 as answer it would have to be 5.0. It was also very strict on empty spaces, so I had to use .trim() everywhere. But the project did help me learn how to do deal with the Arrow Anti-Pattern with neste ...

It was a weird project, but i guess the point was to learn how to follow a program flowchart without question it so much. Anyways it was really fun.
