Thanks for the heads-up. Is C really that different now that I need to worry about it? I have done some work in C++ before, but that was many years ago and I've grown accustomed to high-level languages...
main(){
/* ... */
}
In other places, it puts restrictions that are no longer relevant today. For example, since C99 (and most compilers allowed this long before C99) you can declare variables anywhere inside a block (which is pretty handy), and not just at the beginning of the function.
