    Default How can I do this program?

    Write a program that will find all the three digit natural numbers that are equal to the sum of the cubes of their digits. Maximum 3 digit number is 999. What is the first?

    Cool

    To multiply all digits divide the number by ten and store the leftover in another variable (by using the % operator). Then divide the left number by ten again and so on.

    153; do you really lack the imagination to come up with the condition:

    Java Code:
    	if (100*a+10*b+c == a*a*a+b*b*b+c*c*c)
    in a triple nested loop for values of a in [1,9] and values of b and c in [0,9];
    ... if so, programming is not for you.

    kind regards,

    Jos
