I need help solving two macro questions in C++.
They are:

Define a macro PANIC that expands to code that uses coutÂ* to print the word PANIC and then calls a function quit (with no argumentsÂ*).

I think the answer is

#define PANIC;
cout <<quit();

but the compiler gives me errors.
My second question is:

Define a macro PLUS1 that accepts a valueÂ* as a parameterÂ* and produces an expressionÂ* representing 1 more than the valueÂ*.

My wrong answer was

#define PLUS1 (x)
PLUS1+1

If you know the answer, please tell me - also explain how you got the answer.

Thanks!
C++
