You are required to write
a program to ask the user to input his/her birth month and birth
day, and print out the astrological sign corresponding to his/her
birthday.
 -  You may first design a function 
 int order(int month, int day)
which will determine the number corresponding to the astrological sign.
 -  Then in the main program, you may define a string array
 char* astrological_sign[] = { "Aries", "Taurus", "Gemini",
             "Cancer", "Leo", "Virgo",
		      "Libra", "Scorpio", "Sagittarius",
		       "Capricorn", "Aquarius", "Pisces"
		       };
 so that you can easily print each of them with an index.
 
The program may run as follow:
Input your birth month and day, separated by a space -- 3 31
Aries
Input your birth month and day, separated by a space -- 4 19
Aries
Input your birth month and day, separated by a space -- 4 20
Taurus
Input your birth month and day, separated by a space -- 12 25
Capricorn
Input your birth month and day, separated by a space -- 2 22
Pisces
Input your birth month and day, separated by a space -- 0 0
