Write a function named gcd that takes two positive integer

Question

Write a function named "g_c_d" that takes two positive integer arguments and returns as its value the
greatest common divisor of those two integers. If the function is passed an argument that is not positive (i.e.,
greater than zero), then the function should return the value 0 as a sentinel value to indicate that an error
occurred. Thus, for example,
