Initializing a struct with aggregate initialization and member initializers [duplicate]

Answer 1

In c++ struct and classes are the same, except that structs have default public members and classes have private. If you want to use initial values I think you have to write a constructor or use something like this:

struct ABC
{
    std::string str;
    unsigned int id;
} ABC_default = {"init", 0 }; //initial values

int main()
{
    ABC abc = ABC_default;
    std::cout << abc.str << " " << abc.id << std::endl;
    return 0;
}
