gcd

Your mission

Write a program that prints the greatest common divisor of two strictly positive integers.

See it in action

./gcd 36 48

Expected result

Your checklist

For your own tracking. Tests grade your code.

The program receives exactly two decimal strings that fit in an int.
Print their greatest common divisor followed by a newline.
If the program does not receive exactly two arguments (argc must be 3), print wrong number of arguments followed by a newline.
You may use printf and atoi.
