The distance to the landing point of projectile, launched at an angle angle (in radians) with an initial velocity of velocity (in feet per second), ignoring air resistance, is given by the formula

velocity * velocity * sin(2*angle) distance = __________________________________ 32.2

- Download the program missle_game.cpp
- Note, if you are using IE, please right click on the program, then choose save target as.
- This program ask the user to first enters the distance to target.
- The user then enters the angle and velocity for lunching a projectile.
- If the projectile comes within 0.1% of the distance to the target, the user wins the game.
- If the projectile doesn't come close enough, the user is told how far off the projectile is and is allowed to try again.
- If there isn't a winning input after five tries, then the user loses the game.
- To simplify input for the user, your program should allow
the angle to be input in degrees. The formula for converting degrees
to radians is
radians = degrees * 3.14159265 / 180.0

- Each of the formulas in this problem should be implemented
as a C++ value-returning function.
The sample output of the program should looks like the following:
