i wanted to write a simple program that tell the user zodiac sign and his life path number , the problem is even when given wrong birth date it keep writing the life path number , i am using Euclidean division
exmp 12/02/1999

day 12 = 1 + 2 = 3
month 2 +0= 2
year 1999 = 1 + 9 + 9 + 9 =28= 2 + 8 = 10=1 + 0 = 1

total day +month + year
2 + 3 + 1 = 6

Life Path Number is 6

Code:
