Game Rules

We have three scenarios to consider:

  • Rock vs. Paper -> Paper wins.
  • Paper vs. Scissor -> Scissor wins.
  • Scissor vs. Rock -> Rock wins.

If both players use the same shape, it is considered a draw.

Prerequisites: C++ Basics, Functions, Random Number Generation, Conditional Statements

Components of the Program

The game is implemented with the help of the following components:

  • Header Files: A necessary standard template library has been added for performing operations such as Random number generation, input/output, etc.
  • getResults() Function: It compares the input of the computer and the player and gives the result of 1 for the win, 0 for the tie, and -1 for the loss.
  • getComputerMove() Function: This function uses a random number generator and returns the computer move based on the randomly generated number.
  • main() Function: In this, the main logic of the code is written, the player needs to choose 's' for (stone), 'p' for ( paper), or 'z' for (scissors). Then random input will be generated by the computer and the game function is called. this function will return an integer for the result and based on that result winner will be shown.
