int getValue()
{
int inputValue;
cout << "Enter an integer: ";
cin >> inputValue;
return inputValue;
}
double getValue()
{
double inputValue;
cout << "Enter a floating-point number: ";
cin >> inputValue;
return inputValue;

Did you put using namespace std or using std::cout/ using std::cin?

[Chubby]

Yup I use all the basic of C++ such as #include <iostream> , using namespace...

[Chubby]

is error because of same return type?

[long double main]

Does your code actually compile?
It shouldn't.

You can't overload functions only by return type -- the parameters have to be different.

i got it now!! Thank you

Try using different data type for input parameter even if you don't use it. See if that helps.
int getValue(int a)
{
int inputValue;
cout << "Enter an integer: ";
cin >> inputValue;
return inputValue;
}
double getValue( double a)
{
double inputValue;
cout << "Enter a floating-point number: ";
cin >> inputValue;
return inputValue;

[long double main]

Eh, I don't think that's what parameters are meant for.

If you really want to be able to use getValue for multiple data types, you could just pass the variable in as a reference:

void getValue(int& num)
{
    std::cout << "Enter an integer: ";
    std::cin >> num;
}
void getValue(double& num)
{
    std::cout << "Enter a floating-point number: ";
    std::cin >> num;
}

(or use templates, if you know anything about those)
