How many times per day, in your daily Delphi programming, do you need to solve a specific algorithm - create a custom function / class / object?

For me, most of my programming tasks, when simplified / generalized, include dropping some control on a form, specifying a few properties and handling a few events.

I could say that in some 80% Delphi already has, in the VCL, a control / component that is designed to do what I need it for, it already exposes a function in the RTL library providing the functionality I need.

However, in some 20% I need to write a custom function / class to solve a particular algorithm for my project.

Delphi Programming Exercises: Why Join / Participate?

Delphi programming challenges / exercises are designed to:
  • help you solve a particular Delphi programming task,
  • write a handy Delphi algorithm,
  • refactor your old code to make it more efficient,
  • get new ideas on how to code faster / better Delphi code.
  • and of course: to have fun while coding in Delphi :)

Sometimes asked yourself: "how good a programmer I am"?

Explore Delphi programming challenges and participate!

All levels of programming skills are acceptable. There are no prizes, only fame and glory to see your name in lights ;)

Participate to help others by solving Delphi challenges and others will help you.
