Review, divide two integers

[wolle]

Thanks. Now I've fixed that issue.

Note that there's a distinction between integer types and floating point types in C++. Make sure you fully understand this distinction and the implications.

Regarding integer division. This,

int rest = x / y; // / gives quotient

will give you the quotient (not the rest) of x divided by y. This,

int rest = x % y; // % gives remainder

will give you the remainder (the rest) of x divided by y. if it is 0 then x is evenly divisible by y. That's what you should use in isFactor().
