Menu
I’ve tried every possible loop combination (although i m new to javascripting) and nothing worked. This version has a working loop but stops after user enters nothing and hits OK. Prompt should be asking same question until nothing entered. At that point all the ‘results’ (whatever was entered in previous n prompts) should be retrieved and processed. End result should look like this (if ‘cs a 4’ and ‘bb b 3’ were entered for 2 prompts):
COURSE GRADE HOURS
cs a 4
bb b 3
Total grade points = 28
Number of hours = 7
GPA = 4.000
