Inline Function

 Inline Function

When a class function is defined as a short, minimum line of code, it is called an inline function, but it can only be used when a function body is concise, usually a single line.

Mention that instead of calling the function, its code is inserted directly where it's called.

Highlight that inline functions reduce the overhead of function calls.

Note that inline functions can improve performance, especially for small functions.

inline is keywords, but in both cases, it depends on the compiler. 

Explain that the compiler decides whether to inline the function based on its size and complexity.

explicitly mentioned inline, if a function is too large or complex, the compiler may choose not to inline it.

If not explicitly mentioned, if a function is too small the compiler may choose to inline.
