Some doubts regarding linter in c++

Question

My ide is showing linter error in the following code. It is highliting yellow in the int main() student s; part

using namespace std;

class student {
public:
    int age,DOB;
    char name[32];
    void getData() {
        cin >> age >> DOB >> name;
    }
    void display() {
        cout << name << ends << age << ends << DOB ;
    }
};

int main() {
    student s;
    s.getData();
    s.display();
}

and the following code which is same but on adding curlys after student s in the int main student part solves the problem

using namespace std;

class student {
public:
    int age,DOB;
    char name[32];
    void getData() {
        cin >> age >> DOB >> name;
    }
    void display() {
        cout << name << ends << age << ends << DOB ;
    }
};

int main() {
    student s{};
    s.getData();
    s.display();
}

Answer 1

Your IDE most likely points out that the member variables of s are not initialized.

Using {} syntax ensures that it is initialized.
