How can we create a function of our own to generate random numbers ?

Answer 1

This was the first official assignment I had during my first semester studying CS in my university.

You have to create your own equation to "randomise" the output from a set of integers, probably stored in arrays. If you are prohibited from using any built-in function at all, you may utilise <fstream> to store and alter your seed value and equation each time you start your program so that the values will always be different.
