In this project your task is to implement a playable “Rock, Paper, Scissors” program to play against the computer.

• Our game will be designed for two players.
  • You will be one player
  • The computer will be the other player
• There are three objects which can be played: a rock, a piece of paper, and a pair of scissors.
• The rock will break the scissors (rock beats scissors)
• The paper will cover the rock (paper beats rock)
• The scissors will cut the paper (scissors beats paper)
• Gameplay will consist of three rounds
  • whoever has triumphed the majority of the time will win

• You can design your program so that a certain player always goes first, or have that be picked randomly.
• Computer's choice will be pseudo-random, using the C random number generator.
• your program should display a welcome message and offer to print instructions.
  • This means you will need to accept input from the user on STDIN and properly evaluate it.
• Throughout the program, check for invalid input.
  • Output a message and keep looping until the correct value is entered.
• Upon the user's turn:
  • your program should prompt you for the item you wish to pick
  • You are free to come up with any sort of input scheme (1 for rock, 2 for paper, etc.).
• Upon the computer's turn:
  • you need to print out a message indicating what piece the computer has “chosen”.
• At the end of each round:
  • display who won the round
  • explain how the round was won
• a score needs to be kept, so at the end of the third round, you can display the winner.
• When the game is over, ask the user if they wish to play again.
  • If yes, the game will be played again (3 rounds)
  • If no, the program should exit
