Declaring static variable

makan007 (77)

1 2 3 4 5 6 7 8 9 10


	static int goodAns = 1;
	
	if (goodAns % 2 == 0)
		cout << "Congrats" << endl << endl;
		
	else
		cout << "Good Job" << endl << endl;
		
		goodAns ++;

I need to know is it better to declare static int goodAns = 1 or goodAns = 0?
What is the diff?

It depends on what you need

Hello!

Ok, what don't you understand?

The static keyword ensures that the variable preserves its value between function calling.

The % operator divides the goodAns by 2 and return the fractional part. So 1 / 2 would be 0.5 but it will be made round to 0.

else
		cout << "Good Job" << endl << endl;
		
		goodAns ++;

The goodAns++ instruction is always executed! It doesn't belong to the if statement.
If you want it then you should use braces.
