first time trying to overload a method/member Fx --need help

[ofranko]

i'm trying to overload fx "myAnswer"... i want to return - int
myAnswer when
myAnswer== sumOf ..... when they are != i want the message
"Incorrect..." to be returned..
i've included some of the code ..if you need more just ask..



thank you for your help,
frank

i'll continue working on it..if i get i'll let you know

class AddingNumbers
{
public:
AddingNumbers(int initialRandomNumber, int initialAddTable,
int initialsumOf, int initialMyAnswer);
~AddingNumbers();
int GetRandomNumber();
void SetRandomNumber(int randomNumber);
int GetAddTable() ;
void SetAddTable(int addTable);
int GetsumOf();
void SetsumOf(int sumOf);
int GetMyAnswer();
//string GetMyAnswer();
void SetMyAnswer(int myAnswer);

private:
int theRandomNumber;
int theAddTable;
int theSumOf;
int theMyAnswer;
};

string AddingNumbers::GetMyAnswer()
{
myAnswer ="Incorrect, Try Again ";
cout << myAnswer<<endl;
}
int AddingNumbers::GetMyAnswer()
{
int myAnswer = 0;

cout << "What is the Sum of " << theAddTable <<" + " <<
theRandomNumber << " ?" <<'\n';
cin >> myAnswer;//system("pause");
if (myAnswer == theSumOf)
{
cout << "CORRECT!," <<'\n'<< "Next"<<'\n'<<'\n';
cout << theAddTable << " + " << theRandomNumber << " = " <<
theSumOf << '\n';
//countedCorrect ++;
return myAnswer;
}
else
{
cout <<" Incorrect," <<'\n' << "Next " <<'\n'<<'\n';
cout << theAddTable << " + " << theRandomNumber << " = "<<
theSumOf << '\n';
}
return myAnswer;
}

Joe Cook answered why; a function can only have one return type.

One thing you could do is pass an int by reference to GetMyAnswer(),
and have it return a bool indicating success, passing the answer back
through the int on success, e.g.:


// Returns true if correct, false if incorrect.
// If correct, also stores answer in 'answer' parameter.
bool AddingNumber::GetMyAnswer (int &answer) {

...

if (myAnswer == theSumOf) {
answer = myAnswer;
return true;
} else {
return false;
}

}


Then the usage might be:


int answer;
if (myAddingNumbers.GetMyAnswer(answer) == true) {
cout << "Answer " << answer << " is correct!" << endl;
} else {
cout << "Your answer was incorrect." << endl;
}


There are quite a few ways you could change your design to make it do
what you want, this is just one way.

HTH,
Jason

Is there no chance to implement this problem?

The question asked by ofranko has been answered, it is not possible to
overload by return type in the C++ language.

If you have a new question, this would be a good place to ask it.
