Question

Help plz

Answer 1

?

Answer 2

Pretty hard to find the bug when no code has been presented, & 3 languages to choose from.

Can you be a bit more specific with your question

Answer 3

Your question needs more explanation. But generally, look at the error message given by the compiler(or the interpreter). Line number will be mentioned there most of the times(Some extra information will be given too, try to understand them if you can). Look that the line number mentioned there, and see if you can find something wrong in that line of code.

The error could also be a few lines before or above the line mentioned by the compiler(or interpreter).

If your question was more specific, I could have tried to answer more specific :)
