Statements and the Structure of a Program

Kicked off with lesson 1.1. The big takeaway: a statement is an instruction that does something, and a function is just a named, ordered collection of statements.

Every C++ program needs exactly one main() function — it’s the designated entry point, and execution starts there regardless of where in the file other functions are defined. Coming from RuneScript at work, this maps fairly cleanly onto entry-point conventions I already know, though the explicitness of C++’s compilation model is going to take some getting used to.

int main()
{
    return 0;
}
