What are some alternatives to switch-case in C++?

You can use if-else statements, polymorphism, or even maps for alternatives to switch-case in C++. Would you like examples?

Yes, please provide examples for each alternative.

Sure! For if-else statements, you can check conditions like this:

if (value == 1) {
    // action for case 1
} else if (value == 2) {
    // action for case 2
} else {
    // default action
}

For polymorphism, you can define a base class and override methods in derived classes. Would you like to see a code snippet for that?

Yes, that would be helpful!

Here's a simple example using polymorphism:

class Base {
public:
    virtual void action() = 0;
};

class Case1 : public Base {
public:
    void action() override { /* action for case 1 */ }
};

class Case2 : public Base {
public:
    void action() override { /* action for case 2 */ }
};

Base* obj = new Case1();
obj->action(); // Calls action for Case1

This way, you can dynamically choose the action based on the object type.
