I couldn't agree more, except that please do NOT WRITE TITLES LIKE THIS 

You don't need compilers for any common web development language, you need them for programming languages like C, C++ and C#. If there's compile errors, you need to include the right headers (e.g. libraries with functions), and you may have to fix the code too.

So you need to understand to code too, before you just compile it. If you don't understand the code you're trying to compile, or the purpose of it, the output could be anything. Be smart 

Use Code::Blocks or GCC for C code, use Code::Blocks or G++ for C++ code.

Read a few tutorials on how to use Code::Blocks, it's what I and most people would do before getting pissed  It's the way of learning like a hacker
