[C++] Inline Functions Tutorial

Although I already learned about basic functions in c++ the inline function. Inline functions are not always important, but it is nice to understand them. The basic idea is to save time at a cost in space. Inline functions are a lot like a placeholder. One time you define an inline function, using the 'inline' keyword, everytime you call that function the compiler will replace the function call with the actual code from the function.
