-The function to be used is determined at compile-time from the usage at the call site, as the types of the arguments are always known. A best-match is performed in the case of no exact match, so for example `f('a')` would call `f(int i)` while `f(0.5f)` would call `f(double d)`.

 ## Inline functions
 
-Functions can be declared as inline functions by using the keyword `inline` before the return type in the function definition. The main aim of declaring a function `inline` is to remove the time overhead of a function call; the function body code is replicated for each function call *in place* at the call site(s). Functions declared with `inline` must be present (and identical) in each translation unit that uses them, hence they often appear in header files; this is a special relaxation of the ODR. Overuse of inline functions can lead to *code-bloat*, so they are best reserved for very short functions. The following program demonstrates use of the `inline` keyword:
