cointToss.cpp
Hi Everyone, I am excited about the progress you are making and had fun yesterday talking about the rand() function with loops. I realize programming feels a little scary still, keep practicing, compiling, making sure your programs are up to standard and it will come together.
This assignment mimics tossing a coin. 0 for heads and 1 for tails. The computer will generate a 1 or 0 when using the modulus operator of 2. Then you are to make your “call” 1 for heads, two for tails, and keep track of how many wins for the computers and how many wins for the user. Once you have played best out of seven, you should display the results.
NOTE: make sure the user only enters a 0 or a 1 for their guess
NOTE: make sure the program runs until the game is over.

MathTutor.cpp
MathTutor.cpp
Write a program that can be used as a math tutor for a young student. The program should display two random numbers to be added, such as
247
+ 129
__________
The program should then pause while the student works on the problem. When the student is ready to check the answer, he or she can press a key and the program will display the correct solutions:
247
+ 129
_______
376
Using the while-loop() , Have the program run until the user is finished.

RockPaperScissor.cpp
Write a program that lest the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows.
When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, than the computer has chosen rock. If the number is 2 then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (don’t display the computer’s choice yet.
The user enters his or her choice of “rock”, “paper”, or “scissors” at the key-board. (you can use a menu if you prefer)
The computer’s choice is displayed
A winner is selected according the to following rules:
If one player chooses rock and the computer chooses scissors, than rock wins (the rock smashes the scissors.)
If one player chooses scissors and the computerr chooses paper, then scissors win. (scissors cut paper)
If one player chooses paper and the computer chooses rock, then paper wins (paper wraps rock)
If both players make the same choice, the game must be played again to determine the winner.
Be sure to keep track of the number of wins for the player and computer.
Program should run until the player is finished with the game.
When players is finished running the program, it should display the total wins and determine the winner.

Stock Profit: The profit from the sale of a stock can be calculated as follows:
Profit = ((NS * SP) – SC) – ((NS * PP) + PC)
Where
NS is the number of shares,
SP is the sale price per share,
SC is the sale commission paid,
PP is the purchase price per share, and
PC is the purchase commission paid.
If the calculation yields a positive value, then the sale of the stock resulted in a profit. If the calculation yields a negative number, then the sale resulted in a loss.
Write a program (using appropriate functions) that accepts as arguments the number of shares, the purchase price per share, the purchase commission paid, the sale price per share, and the sale commission paid. The function should return the profit (or loss) from the sale of stock.
