Hello I'm not sure if this is a beginners forum, but I will start here. I am a beginning C++ student and have a couple of mini-projects invloving fractions that I need some guidance on. First the assignments: 1. Write a Fraction-Reduction program that takes in any fraction (maybe with denominator not equal to 0 or 1), and reduces it lowest terms. The function prototype will take two integer variables passed by reference. 2. Write a function that takes in any number and returns its whole and fractional parts as outputs. Like 6.44 would return int 6 and float 0.44. My trouble: On #1: I understand how reference passing is working, that the variables values in main's variables can be changed by the function. What I cant figure out is how to write something that will find the greatest common factor of any two numbers entered. I understand the math behind it but I cant translate that math to the program, and get it the correct place in main or the function and have it work. On #2: This problem came from the chapter on reference parameters also. So is there a way to do this problem with the user entering one single float? Or is the trick to cin what the user enters in a format that allows to be updated invidually by reference from a function? If my code is needed I can post it. If there is another forum I need to be at, please let me know. Thank you sincerely for any help. JB
