    • The C++ inline function provides an alternative. • With inline keyword, the compiler replaces the function call statement with the function code itself (process called expansion) and then compiles the entire code. • Thus, with inline functions, the compiler does not have to jump to another location to execute the function, and then jump back as the code of the called function is already available to the calling program.

    When the inline function is called whole code of the inline function gets inserted or substituted at the point of inline function call. This substitution is performed by the C++ compiler at compile time.

    If a program uses Inline Function, then the function is expanded inline at compile time. Inline function is best, when the function size is less.
