I'm pretty sure that my C program either won't compile, or won't do what I want if I treat curly braces and semicolons as you are treating python indentation.

I'm pretty sure that my C program either won't compile, or won't do what I want if I treat curly braces and semicolons as you are treating python indentation. They serve the exact same purpose, and are both necessary, but the choice of braces versus whitespace is purely aesthetical.
