Lesson 48/120

A request to the compiler to replace function calls with the actual function code to eliminate call overhead.

SYNTAX

inline int max(int a, int b) {
    return (a > b) ? a : b;
}

PROS

Eliminates stack push/pop overhead for small functions.

CONS

May increase binary size (code bloat) if function is large.

COMPILER DISCRETION

inline is only a suggestion. The compiler can ignore it for complex functions containing loops, recursion, or static variables.
