Why compiler can not execute this code?

Question

Hi guys, I d gone crazy doing this program on my computer but when I pasted it in Sololearn compiler, it printed: Compiler error even it had worked on DevC++. Maybe because I used both C and C++?

Answer 1

Yeah, that is the issue. Sololearn can't read c and c++ at the same time. Try swapping printf for cout and gets for cin.

Answer 2

Even my Python codes don’t work on SoloLearn.

Answer 3

Julien Quentin, if you d read more carefully, I 've written that everything is valid on my compiler on a computer )
