Hi. I need some help with iteration. What we need to do is to ask for 4 parameters from the user. The program will compute for A, B, C, D, E, F, and A_new. After one iteration, the program will use A_new as A and the process repeats until the difference between two A_new's is less than 0.001. How can I make this into a nested loop? We tried doing two do-while loops but the program just won't compile. Thanks in advance.
