Topic:

The problem description is known as a rational number class Zrf_ratio, which implements the following operator overload form:
Friend std::ostream& operator<< (std::ostream&, const zrf_ratio&);//output minimal fraction
Friend std::istream& operator>> (std::istream&, zrf_ratio&);
friend bool operator== (const zrf_ratio&, const zrf_ratio&);
friend bool operator< (const zrf_ratio&, const zrf_ratio&); When testing the test, the main program enters four integers a, B, C, D, representing two fractions of A/b and C/D. Requires the output of the simplest fraction and a comparison of two fractions equal and size. Sample Input 1 7 26 25 sample output ZRF IS:1/7; SSH IS:26/25
(ZRF==SSH) is:0; (ZRF&LT;SSH) Is:1 Blue Bridge Cup is really very broken I submit the code always compile the error point in the evaluation actually in my code appended to the previous submitted code together without words AH!!!!!!!!!!!!!! Always compile error I want to get angry
