Question

I have 3 classes, lets say ClassA, ClassB and Validator. I want to pass one variable of both classA and classB to the Validator, which will compare the values, and return a string result. I get the following error: error:

request for member ‘compareValues’ in ‘validatorObject’, which is of non-class type ‘Validator*’

main.cpp

cout << classAobject.compareValues(computer1->getValue(), classBobject->getValue());

validator.cpp

string Validator::compareValues(string classAvalue, string classBValue) {
if (classAvalue == "R") {
    if (classBvalue == "R") {
        return "Equal";
    }
}
// More will go in this function - just want to get it working first

}

validator.h

string compareValues(string classAvalue, string classBValue);

Answer 1

This error appear because you need to access class member from pointer to class by using -> operator: cout << classAobject->compareValues(.....)

Foo->bar() is equivalent to (*Foo).bar(), and Foo->baz is equivalent to (*Foo).baz
