[Problem solved] Why doesn't sololearn code playground work as vscode or other ides do?

Question

I wrote the first code on vs code and checked if it worked or not as expected. It was pleasing to get no errors there. Then I copied the code and run it on sololearn. And ended up getting the warning:
"Expected expression before float"

My question is, why isn't it working here although it was working on vscode?

Answer 1

As I understand it, casting in C is done as follows

(target-type) data

So the problem in line 27 is the way you cast `int` <letters> into `float`, which should be

int average = (int)ceil ( (float) letters / words );

Answer 2

Well, that's because Sololearn uses a different compiler than the one you use in VSCode and the way you cast is not the correct one.

Answer 3

Thanks for recorrecting Edgar Sabido and Ipang !
I surely should have checked again whether my code was correctly written or not
