        Create a program that will ask the user for the length of their desired array. Let us limit it from 20 to 100. Then ask them a seed and an increment.

        On every index of the array, you will be generating a random number that will generate a random number between x and y.

        x = the lower limit which is either 0 or the value of the increment before it

        y = y + increment * (index)

        Fill up the entire array like this.
