Read a rational number (1) P59652

Write a procedure

    void read_rational(int& num, int& den);

to read a rational number given in the form “numerator”/“denominator”, and store these two values in @num@ and @den@, respectively. Additionally, you must remove all common factors from @num@ and @den@. For instance, if the input has

66/12

the values after the call must be @num@ $= 11$ and @den@ $= 2$.

Precondition

$1 \le$ @num@ $\le 10^9$ and $1 \le$ @den@ $\le 10^9$

Observation

You only need to submit the required procedure; your main program will be ignored.
