How can I use consts in C++ structs?

You can use const members in C++ structs to define constant values that cannot be modified after initialization.

Can you give me an example of a struct with const members?

Sure! Here's an example:

struct MyStruct {
    const int id;
    const std::string name;

    MyStruct(int id, std::string name) : id(id), name(name) {}
};

In this example, id and name are constant members.

What happens if I try to change a const member after initialization?

If you try to change a const member after it's initialized, you'll get a compilation error. const members are immutable.

Are there any limitations to using consts in structs?

Yes, you cannot assign values to const members after the struct is constructed, and they must be initialized in the constructor.
