    Question How to generate random numbers between 0 to 7 using a function that generates 0 to 3

    My line of thought is to use Left shift of bits. Maybe call the function twice.

    What would be the most efficient way?

    I think you're headed in a right direction.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Maybe throw in an xor there too...
