Answer 2

I think it would take longer to tell me what to find...just search Codes with words like: 'shapes', 'circle', 'diameter' then skim the icons for your language: Java, c++, c#...

Point is, SoloLearn has examples...hopefully enough inspiration to quickly write your own.

'shapes' - first ~15 results (just for inspiration):
