If anyone knows how to use this program, we need to make a fraction quiz and the teacher won't tell us anything. So far I just have 3 different numbers with 1 underneath the other two, but if theres a way to make it one character, I'd appreciate the help. something like: a + b - - c c I think I'm going to do the math outside the fraction and just check for the correct answer, unless someone can give me a more correct way to do it. |

so, you need an input (3 numbers: Numerator and Denomenator) and an output (mixed number or decimal)? |

we're supposed to generate 3 random numbers for easy difficulty, and 4 for medium and hard (different bottom numbers, can't think of the word). fatass teacher wrote: Quiz phase 3
Expand the current quiz program to include add, subtract, multiply, and divide of fractions. All answers received from the user must be in simplified form. Improper fractions are acceptable. No mixed numbers. Show the fractions as they would see them in a math book. The easy quiz should be the only one in which like denominators already exist. Medium and hard should have unlike denominators. Earlier we had to just make two numbers for + - x and /, and now must do fractions. I can generator the 4 random numbers fine, but I'm not sure how to make it so they go together evenly for multply and divide. |

why not just follow the basic rules for multiply and divide fractions...? http://www.aaamath.com/fra.html#topic23 Here is the program... http://www.cplusplus.com/src/fraction2.zip One thing i learned from college is there is an example of every program on the internet it seems. I just chose to learn from google instead of a 300$ text book. |

you basically need to take in 2 fractions in the form of "x / x" and put them into an array of characters. to add, you find the common denominator by multiplying the smallest denominator by the largest denominator, and the opposite for the larger denominator. you then multiply the numerators of both by the same number as you did w/ the denominator, and add them together, and move that answer to your solution array. subtraction is the same concept. to multiply, just multiply the 2 numerators and store that into the numerator of the solution, and the same for the denominator. to divide, invert the 2nd fraction and multiply |

well, the one link you gave me, the program samples it gives have 25+ errors  and I'm not sure whats all wrong other than it might be a different version. I went to the website and click fractions 1, and that worked, but it only simplified fractions that the user inputed.
in the end, i wasted all day making part of my program look silly, and I guess I'll figure it out monday. p.s. thanks for the snow yarr |

we gotta use a command called modulus (%) but the teacher won't tell us how to use it. it makes sure numbers divide into each other evenly. |
