Read a rational number (2) P93157
Write a procedure
bool read_rational(int& num, int& den);
that tries to read a rational number given in the form “numerator”/“denominator”, and stores these two values in num and den, respectively. Additionally, you must remove all common factors from num and den. Furthermore, if the input had a rational number, you must return true; otherwise you must returna false. For instance, this code
int num, den;
while (read_rational(num, den)) cout << num << ' ' << den << endl;
with this input
66/12 100/100
should print
11 2 1 1
Precondition
1 ≤ num ≤ 109 and 1 ≤ den ≤ 109
Observation You only need to submit the required procedure; your main program will be ignored.
