==A Demonstration of an Inline Function==

<source lang="cpp">#include <iostream>
inline int Double(int);
int main()
{
int target;
using std::cout;
using std::cin;
using std::endl;
cout << "Enter a number to work with: ";
cin >> target;
cout << "\n";
target = Double(target);
cout << "Target: " << target << endl;
target = Double(target);
cout << "Target: " << target << endl;
target = Double(target);
cout << "Target: " << target << endl;
return 0;
}
int Double(int target)
{
return 2*target;
}</source>

==function inlining==

<source lang="cpp">#include <iostream>
int radiation(int health);
using namespace std;
int main()
{
int health = 80;
cout << "Your health is " << health << "\n\n";
health = radiation(health);
cout << "After radiation exposure your health is " << health << "\n\n";
health = radiation(health);
cout << "After radiation exposure your health is " << health << "\n\n";
health = radiation(health);
cout << "After radiation exposure your health is " << health << "\n\n";
return 0;
}
inline int radiation(int health)
{
return (health / 2);
}</source>

==Inline Functions==

<source lang="cpp">#include <iostream>
using namespace std;

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

int main()
{
cout << max(10, 20);
cout << " " << max(99, 88);

return 0;
}
// As far as the compiler is concerned, the preceding program is equivalent to this one:
/*
#include <iostream>
using namespace std;

int main()
{

cout << (10>20 ? 10 : 20);
cout << " " << (99>88 ? 99 : 88);

return 0;
}
*/</source>

==Inline functions work best on short functions that are used repeatedly. This example calculates the square of an integer.==

<source lang="cpp">#include <iostream>
using namespace std;
inline long squareit(int iValue) {return iValue * iValue;}

int main()
{
int iValue = 5;
cout << squareit(iValue) << endl;
return (0);
}</source>
