Question - 7) What are inline functions ? What is the advantage of using them ? How are they declared ?

Answer: An inline function is a function upon which the C++ compiler is asked to perform inline expansion, i.e. the compiler is requested to replace every function call with the complete body of the function, rather than generating the function code at each and every position of the function call.

The major advantage of inline functions is that it saves on the overhead of a function call. Since the function is not invoked, but its code is replaced in the program, it saves the compiler time and improves efficiency.

The format to declare an inline function is:

inline datatype function_name(parameters)
{
function content;
}
