Question

Program specifics:

Write a C++ program that does the following:

a. Asks the user for the distance to the pin and the depth of the green (both in yards). (Note: The pin is the hole in the green and the depth is the diameter of the green, assuming it is circular.)

b. Asks the user for an integer club number from 2 to 10, where 10 is the pitching wedge (this club lifts the ball out of rough, sand, etc). If the user enters an invalid club number, the program prints a warning and asks for the club number again.

c. Asks the user for a swing type, from 1 to 4, where 4 is a full swing, 3 is a three-quarters swing, 2 is a half swing, and 1 is a quarter swing. The program should check to make sure the swing is a valid number and if it is not, allow the user to try again. There is no requirement to limit the number of guesses of either the club type or swing strength,

d. Uses the following constants - a1, b1, a2, b2, a3, and b3—that are embedded into the following equations: Golf Constants for the program A              B 10.2        3.27 53.5        -1.75 19.6       4.89 clubangle(degrees) = a1 + b1*0.85*clubnumber; (see figure at right) clublength(inches) = a2 + b2*1.05*clubnumber; (see figure at right) clubspeed(yards/s) = 1.1 * (a3 + b3 * swingnumber) * (clublength(inches)/40)^2;

e. Determines the distance the ball travels, how far it lands from the hole that is on the green (the "pin"), and whether it hits the green. You can assume the ball travels perfectly straight, there is no wind resistance, and the pin is in the center of the green. To determine the distance the ball travels, use the following equation:

       distance = club speed^2 * sin(2*club angle in radians)/g

     (g = 32.2 ft/s² is the acceleration of gravity in English units—make sure you convert your units correctly to get distance in yards).

f. The program reports to the screen, in a well-formatted table: the club used, the swing number, the distance the ball travels, the distance from the pin that the ball hits the ground (i.e., the error or accuracy), and "Yes" if the ball hits on the green, or else "No". Assume that the ball does not roll after hitting the ground (really wet ground).

g. The table must have appropriate labels.

h. If the ball does not hit the green, the program continues to ask the user for another club number and swing speed.

i. If the club number entered is 99, the program ends
