Question

I'm trying to write this program in C++ and I'm having trouble initializing the overload function I have to use. Here's the assignment and what I got so far, thanks for the help!

/*2. Implement the game of Rock-Paper-Scissors in C++, where you can play against the computer.
a. Scissors beat paper, paper beats rock, and rock beats scissors. If both you and computer choose the same tool, it is a tie.
b. Your program should have a class game with one variable winCount and public functions to set and access winCount.
c. Create another class tool that inherits from game with one private property type.
This class should have appropriate methods or constructors to set and access the property type (for tool type r, p or s).
d. User will select a tool by entering a type r, p or s for rock, paper or scissors.
e. Computer will select a tool by generating a random number between 1 and 3. Random number 1 means r, 2 means p, and 3 means s.
Hint: To generate a random number between 1 and 3, you will need to include header file cstdlib and run the following statement:
int randomNumber = (rand() % 3) + 1;
f. Your program should produce an output like this:
**Enter e to end*** Enter a tool (r, p, s): p. You chose paper. Computer chose scissors. Computer wins... Your winnings: 0 Computer winnings: 1
**********************************. Enter a tool (r, p, s): s. You chose scissors
Computer chose scissors
It's a tie...
Your winnings: 0 Computer winnings: 1
**********************************
Enter a tool (r, p, s): r
You chose rock
Computer chose paper
Computer wins...
Your winnings: 0 Computer winnings: 2
**********************************
Enter a tool (r, p, s): s
You chose scissors
Computer chose paper
You win!!!
Your winnings: 1 Computer winnings: 2

Code is below
