Hey, I'm trying to make a program that has four static methods (including main) that will ask if the person wants to make a parallelogram, a triangle, or quit the program (in the main method). Then its supposed to go to another method to ask for the dimensions (height and width for Parallelogram and just Height for Triangle). There is a certain range of numbers it has to be in-between (in the form of iLowerBound and iUpperBound), and the method has to close after three unsuccessful attempts. Then its either supposed to go to a parallelogram method to draw the parallelogram with those dimensions from the other method, with stars (*), or it will go to the triangle method and draw the triangle with dimensions from the previous method, with random chars.
I am having problems with the getValidInt method (Seen Below) where I can't figure out how to transfer the number range (Parallelogram height (1-40), width (1-60) and Triangle Height (1-30)) into this method. And i am not sure how to set the 3 tries and exit thing either.
Can Anyone Help Me Out?
