Question

Instead of doing the following everytime

start();  // some code here  stop(); 

I would like to define some sort of macro which makes it possible to write like:

startstop() {  //code here  } 

Is it possible in C++?

Answer 1

You can do something very close using a small C++ helper class.

class StartStopper { public:     StartStopper() { start(); }     ~StartStopper() { stop(); } }; 

Then in your code:

{     StartStopper ss;     // code here } 

When execution enters the block and constructs the ss variable, the start() function will be called. When execution leaves the block, the StartStopper destructor will be automatically called and will then call stop().
