Inline function is a function that is expanded in line when it is called. 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. Inline function is used : When the performance is required. It is used outside the class so that we can hide the internal implementation of the function. It doesn't require any stack on which we can push or pop the variable as it doesn't perform function calling. Program to illustrate inline function : #include<iostream> using namespace std; inline float mul(float x, float y){ return(x * y); } inline double div(double p, double q){ return(p / q); } int main(){ float a = 12.345; float b = 9.82; cout << mul(a,b) << endl; cout << div(a,b) << endl; return 0; } The output of above program is 121.228 1.25713
