problem is that i cant get my "else" to work. i tryed it with only the if and got it kinda working. after you put your lenght in, it jumps to "what is your name" and the tells if bmi is goo or bad and then to "press any key to continue...."

	bmi = (meter*meter) / kg;

	while(true);

		{
			cout << "great";
		}
	}


	system("pause");
	return 0;

The problem is on line 27, you put a semicolon after the if statement which is the cause of the error you are experiencing with your else statement. Remove the semicolon at the end of that line and your else statement should work.

Note: You have the same issue on line 25 with your while statement.

The while loop condition of true is never changed, so there's an infinite loop. Do you need a loop? Are they supposed to be able to input details for multiple people?

Why declare global variables at lines 6 and 7 instead of declaring them locally in the main function?

remove your while and it will work fine.
