I'm starting to study OOP now and it's kind of weird to me. But I would like to know if I pass some parameter in a get method, can it result in some error?
Ex:
class MostraNum
{
private:
int x;
public:
int getRetornaNum(int x)
{
return x;
}
};
int main()
{
MostraNum result;
cout<<result.getRetornaNum(100)<<endl;
return 0;
}
No,
Get is just a name used by convention and does not mean anything.
Your function will return the passed parameter and not the member variable 'x' because c ++ prioritizes local variables when the name is the same, if you want to return the member variable x should do explicitly:
return MostraNum::x
But for organization reasons and to make it easier to read your code, give your member variable a special name and do not use repeated names, such as #
