Description
3 Do each of the following:
a) Write the function header for a function `exchange` that takes two pointers to floating-point numbers `x` and `y` as parameters and does not return a value.
b) Write the function prototype for the function in part (a).
c) Write the function header for a function `evaluate` that returns an integer and that takes as parameters integer `x` and a pointer to function `poly`, which represents a function that takes an integer parameter and returns an integer.
d) Write the function prototype for the function in part (c)
![6. Write a program to determine the maximum height to which a projectile will travel if atmospheric resistance is neglected, for different initial velocities. This problem demonstrates the use of repetition controlled by a terminating limit. Method: The mass of the projectile is m, the initial velocity is v0 m/sec, the last initial velocity is vft/sec. From equations of motion: w=mg, Fz=maz. Applying these equations for the projectile results in the following equations: mg=mac gives ac=g. Initial conditions: s0=0, v0=v. Final conditions: sf=h, vf=0. From Kinematics: vf2=v02+2ac(sfs0) 0=v2+2ac(h0) 2ach=v2 h=2acv2 Data: Real values of initial velocity at 50, 100, 150, and 200 ft/sec. The real value of gravitational acceleration is 32.2 ft/sec2. 7. Write a program to compute and print a table of torsion shear stresses for circular rods having various torsion loads at various offsets. This problem demonstrates the use of nested repetitions. Data: Diameter: 5 and 6 inches. Load: 1000 and 12,000 pounds. Offset: 10, 15, and 20 L. Method: Let D = diameter of the rod. P = torsion load in pounds. L = offset. The torsion shear stress is given by the formula Ts = D^3/(16PL). 8. Write a program that reads numbers from an array and graphs the information in the form of a bar chart or histogram. The number is printed first, and then a bar consisting of that many asterisks is printed beside the number. Note: The define size of the array is 10. Example: [Number]: ********** [Number]: * [Number]: ********* [Number]: ***** [Number]: ********** [Number]: **** [Number]: ** [Number]: ******* [Number]: ******** [Number]: *******](https://gotit-pro.com/wp-content/uploads/2023/10/6c588a25-0ba0-4cf2-9cb7-5cd4974446e7.png)
![(b) Modify the program in Q3(a), with the following new rules: - Players will need to win 3 games to become the overall winner. - Implement a penalty - for the player who skipped, entered an incorrect expression, or entered an expression that evaluated to the wrong result, will draw 2 random digits into their hand. - The player who loses the game will be awarded a "Skip" card in the next game. With the "Skip" card, the player can hit < Enter > to skip, without a penalty. - If not utilized, the "Skip" cards CANNOT be carried forward to the next game. Illustration of the "new" game on the left column, with the rules of the game explained on the right column: Enter player: Alan Enter player: Betty Enter player: Starting hand (number) of digits: 4 Let's play... Game 1 Round 1: Result 6 Betty's hand: [5,2,1,1] Enter expression: 5+1 Correct! Betty's hand: [2,1] Alan wins this game in 4 rounds!! Overall game score: Alan 1, Betty 0 Let's play... Game 2 Round 1: Result 5 Betty's hand: [3, 6, 5, 7, 'S'] Enter expression: Skipped with no penalty!! Betty's hand: [3,6,5,7] Alan's hand: [2,1,2,1] Enter expression: Skipped and 2 digits added to hand Alan's hand: [2,1,2,1,4,7] Betty wins this game in 5 rounds!! Overall game score: Alan 1, Betty 1 Let's play... Game 3 Round 1: Result 6 Betty's hand: [1, 2, 8, 7] Enter expression: 8-2 Correct! Betty's hand: [1, 7] Computer randomized the play sequence and will stay the same for every game/round End of game, if no overall winner, continue to play another game. Loser will be awarded a "Skip" card in the next game. "S" represents the "Skip" card awarded to Betty. No penalty for Betty as she has a "Skip" card. Hit < Enter > key to skip if cannot form an expression. In this case, the player who skipped will draw 2 random digits into their hand. End of game, if no overall winner, continue to play another game. Loser will be awarded a "Skip" card in the next game.](https://gotit-pro.com/wp-content/uploads/2023/10/1fa83cc6-5755-4d51-b5f6-f4335b49f1c8.jpg)
