To do: Doubling the given integer to demonstrate the inline function in C++ programming

To show: How to declare, define and use the inline functions in C++ programming

// demonstrates the inline functions

#include <iostream>

using namespace std;

// inline function, no need a prototype here, we directly declares and defines the function

inline int Doubler(int target){return (2*target);}

int main(void)

{

int target;

cout<<"Enter a number to work with: ";

cin>>target;

cout<<"\n";

// function call

target = Doubler(target);

cout<<"\nFirst time function call, Target: "<<target;

// function call

target = Doubler(target);

cout<<"\nSecond time function call, Target: "<<target;

// another call

target = Doubler(target);

cout<<"\nThird time function call, Target: "<<target<<endl;

return 0;

}

Output example:

Enter a number to work with: 100

First time function call, Target: 200

Second time function call, Target: 400

Third time function call, Target: 800
