Lame. Doesn’t let you input data after build/compile

I purchased the unlimited Compilations thinking that while I’m learning how to program C, I could test out some code. However, I was wrong: The problem is that if you write a program that asks for user input, i.e. the “scanf()” function, this App will not let you input data. It is basically a glorified “Hello World”, one-way transmission compiler. No ability to interact in the console. Therefore, very impractical to the vast number of possible uses one might want for C programming.
