Does C++ function overloading apply to member functions?

Yes, function overloading works for member functions, subject to the following restrictions: Overloaded member functions must have different parameter signatures (type and number). Overloaded member functions cannot have the same return type and different parameter signatures.

#C Does function overloading apply to member functions?

Introduction

Function overloading allows us to create functions with the same name but different parameter lists in the same class. However, when it comes to member functions, things get more complicated.

Function overloading that applies to member functions

Function overloading does apply to member functions, but this has some limitations:

• Overloaded member functions must have different parameter signatures (parameter types and number).
• Overloaded member functions cannot have the same return type and different parameter signatures.

Practical Case

Consider the following example:

class MyClass {
public:
    void print(int x);
    void print(double x);
};

Here, the print function is overloaded, once Accepts one int parameter, one double parameter at a time.

Note

• When we try to overload members that only have the difference between const and volatile modifiers function, ambiguity may arise.
• Function overloading cannot be used with default parameters.
• Overloaded member functions cannot be template functions.

Conclusion

In general, function overloading is suitable for member functions, but it is subject to certain limitations. By understanding these limitations, we can use function overloading effectively in C code.
