Question

int calcFactorial::calcSum(int one, int two, int three)
{
cout<<"enter a positive integer"<>num; fact=((num*factorial)(num-1)) ; cout<<"sum:"< 14 years ago

Answer 1

What are the error messages?

Are `num' and `factorial' global? They aren't defined within the method, so that may be the issue.

A possible ZeroDivison Error can occur when num is equal to 1, in the line `fact = ((num*factorial)(num-1));'

Answer 2

are `num' and `fact' declared ** typo sorry (I said factorial instead of fact )

Answer 3

fact, factorial and num ( in the posted code ) aren't defined properly.

A class is it's own namespace, so cout and cin aren't defined, you probably want std::cout, std::endl and std::cin.

one, two and three aren't used, that's probably just a warning.

In the line: fact=((num*factorial)(num-1)) ;
there's no operator between the two sets of inner parentheses.
