#define, #ifdef, #endif to remove cout code

[jazpearson]

I'm trying to figure out how to use: #define, #ifdef, and #endif with my code (with no luck).
During debug, i want the couts in there to appear, but then i want a quick and easy way to remove/comment out any of the cout arguments there. For example, how would i incorporate it into this:

#define // <----- what in here?
#ifdef // <------ something that looks at cout?
#endif // <------- goes here, or below main body of code?

int main(){

float x = 10;

cout << "x = " << x;

return 0;

}

Usually it's like

#ifdef _DEBUG
cout << "x = " << x;
#endif

but what if i had multiple entries of couts all over?

[Disch]

#ifdef _DEBUG
#define DEBUGPRINT(x)  cout << x;
#else
#define DEBUGPRINT(x)
#endif

//...

int main()
{
  DEBUGPRINT("x = " << x);
}
