To create a constructor for a C++ structure?

C and C++ structures look similar, but they are actually different data structures.

In C++, class and structure are

Only the is different, and the other functions are the same.

Therefore, when defining the constructor of a structure in C++, you can write the name of structure just like class.

:

struct foo{
    int a, b;
    foo() : a(0), b(0) {
        cout << "foo made" << endl;
    }
};


int main(){
    struct foo f1;
}
