Thread: wont output my data table

then i noticed that if you dont hit the green its supposed to loop back to a certain point but it was going to far back

Wait, it went too far back? In the original code, you wrote the top of that while loop near the beginning of the program. The program is supposed to go back to the line with the condition on it, test the condition, and then execute the code in the body (again).

so i put a goto statement in

Well, that's wrong. Why didn't you just move out the code that wasn't supposed to execute in the loop?

and now it wont output my data table. not sure how to fix it please help!

Well the table code needs to be put in the loop too. That's my guess. It wouldn't make sense for the table to be printed after you hit the pin, for example, with the way the instructions sound.

Anyway, I moved some code around. You'll notice the goto is now missing. Is this close to what you want?

Code:

// B.Lukacs		EGR 111		Project Golfer		Feb 12 2015
/* This program asks the user for the distance to the pin and the depth of green
  (both in yards) */
/* The program asks the user for an integer club number from 2 to 10 where 10
   is the pitching wedge */
/* If the user enters an invalid number, the program prints a warning and asks
   for the club number again*/
// The program asks the user for a swing type from 1 to 4 (quater to full swing)
/* The program reads from a file that contains the constants for the following
   equations */
//
//		club angle (degrees) = a1 + b1 * 0.85 * clubnumber
//		club length (inches) = a2 + b2 * 1.05 * clubnumber
//		club speed (yards/s) = 1.1 * (a3 +b3 + swingnumber) * (clublength/40)^2
//
/* The program determines the distance the ball travels, how far from the pin
   it lands, and whether it hits the pin or not */
//
// The program determines how far the ball travels using the following formula
//		
/*		distance = club speed^2 sin(2 * club angle in radians)/g 
		where (g) is 32.2 ft/s^2 */
		 
/* The program outputs a table showing the club used, the swing number,
   the distance the ball travels, the distance the ball lands from the pin,
   and "YES" if the ball lands on the green, or else "NO" */

/* If the ball does not hit the green the program asks for another club number
   and swing speed */

// If the club number 99 is entered, the program ends
