a number is perfect if it is equal to the sum of its proper divisor.. 6 is perfect number coz its proper divisors are 1,2 and three.. and 1+2+3=6... a number is deficient if the sum of its proper divisor is less than the number.. sample: 8 is deficient, coz its proper divisors are 1,2 and 4, and 1+2+4=7. abundant number, if the sum of its proper divisor is greater than the number.. sample..12 is abundant coz 1+2+3+4+6=16 which is geater than 12. now write a program that prompts the user for a number, then determines whether the number is perfect,deficient and abundant..
