Inline function __ function

inline function C + + unique, expanded internally, similar to define, but type checking for data types

The inline function simply advises the compiler, and in general, the inline function has the following limitations:
(1) cannot have recursion
(2) cannot contain static data
(3) cannot contain loops
(4) cannot contain Swich and goto statements
(5) cannot contain an array
If an inline function does not meet the above limit, the compiler will treat it as a normal function

#include <iostream>
#include <stdlib.h>
using namespace std;

#define MYPOWER (n) n*n*n

inline int mypower2 (int N) {return
	n*n*n;
}

int main () {
	cout << mypower (3) << Endl;
	cout << Mypower2 (3) << Endl;
	System ("pause");
	return 0;
}
