3. Logic and If Statements

A common task in programming is to perform an operation if a particular logical condition is met. For example, imagine you are playing a game of rock-paper-scissors. If we were to write a program to help us play the game then it would be something like the following.

- The computer chooses a random shape from rock, paper or scissors
- The player chooses one of rock, paper or scissors


- If the player has chosen rock then 
  - If the computer has chosen scissors then
    - The player wins
  - Else 
    - The computer wins

- Else if the player has chosen paper then
  - If the computer has chosen rock
    - The player wins
  - Else 
    - The computer wins

- Else if the player has chosen scissors then
  - If your computer has chosen paper then
    - The player wins
  - Else 
    - The computer wins

This is an example of pseudocode which is a way of outlining the main steps of a program without using specific language syntax.
