Beginning C++ Game Programming

Random numbers

Random numbers are useful for lots of reasons in games. Perhaps you could use them for determining what card the player is dealt, or how much damage within a certain range is subtracted from an enemy's health. As hinted at, we will use random numbers to determine the starting location and the speed of the bee and the clouds.

Generating random numbers in C++

To generate random numbers we will need to use some more C++ functions, two more to be precise. Don't add any code to the game yet. Let's just take a look at the syntax and the steps required with some hypothetical code.

Computers can't actually pick random numbers. They can only use algorithms/calculations to pick a number that appears to be random. So that this algorithm doesn't ...
