From: Alex Untitled on 14 Nov 2009 21:54 I want to create a program that asks you to guess a number between two numbers. The problem is that I can't figure out how to make the numbers that you're guessing between random and have the random number you are guessing between those two numbers. Does anybody know how to do this? -- Posted via http://www.ruby-forum.com/.

Does anybody know how to do this? Well, you know how to generate the first two random numbers, right? Just take the difference between those two as the range in which to generate the third. Simple.

OK, that didn't work. That just added the two numbers. How do I make a number between two numbers again? I can't seem to find it. -- Posted via http://www.ruby-forum.com/. |
