16. Hour 3: Lab 8.1 Coins and Snakes
(Programming Exercise #7 on pages 557 of Starting Out with Games and Graphics in C++) What is the purpose? This lab allows you to work with C++ arrays to efficiently create, store, and retrieve game elements. What are the steps? Task 1: Coins and Snakes (Programming Exercise #7) Procedure 1. Create a new project based on the WalkingAlec.cpp sample. I will give you a starter file. (Program from pages of the textbook) 2. Change the program so that it displays 10 rocks. 3. When Alec collides with a rock, the rock should turn into either a coin or a snake. Score one point for finding a coin and subtract one point for finding a snake. 4. After all the rocks have been hit, the game should end. 5. Display a final score screen.
