[luau] C program question

[Dean Fujioka]

What i usually use in C++ is a separate header file with

void PressEnter(istream& ins, ostream& outs)
{
outs << "Press Enter to Continue.";
getline(ins, '\n');
cin.ignore(100, '\n');
}

then call it with

PressEnter(cin,cout);

p.s this is from memory, I don't have the code i use in front of me, but I
can repost that later if you like. (if this doesn't compile)
