    school project help

    for my shcool project, i am supposed to write a console application program where you can enter a fraction in the form of n/d (numberator/denominator). then when you enter that, the program is supposed to divide the numerator by the denominator. then the prog should give you the quotient, but if it is a repeating decimal (i would just assume that anything above 8 decimal places is repeating) the program is supposed to show the repeating quotient as follows. lets say you typed in one third which is a repeating .3
    it should display it as .(3)

    1/3 [ENTER]
    .(3)

    how do you get the string input in the beginning to recognize n/d as two integers and then how do you get it to display a repeating decimal like .(3) I'm not sure how to get it to display it with the decimal point and then the parenthesis

    now im tired from typing such a long thread. i feel like a noob

    in your shoes, i would eat up the n/d with fgets and parse it into two strings, n and d - then use atoi to convert them to integers

    the repeating decimal place will be tricky to deal with, but sprintf and %f will likely be your friend in this

    Anyway, just to clarify:

    repeating decimals wouldn't be hard and you could prove it not just out 8 decimals. If your remainder after division stays the same twice in a row it is repeating
    1/3

    10/3 = 3 remainder 1 carry decimal 10 10/3 remainder 1

    its not nessecarily twice in a row; for example what about 1/17?

    what about 1/ 17 do you mean the double 8 in it
    Code:
    0.058823529
    the numbers are the same but 150/17 then the next 8 is 140/17 different remainers

    i mean your statement that when you see the same remainder twice in a row, you have found a repeater. 1/17 does repeat, but it never has the same remainder two times in a row (right next to eachother).
