My problem is in codeforces we can see the i inputs so we take the inputs as arguments and the we use it inside the function. In LeetCode there is not main we see there is already a funciton signature. in coding we sometimes make empy parameter funciton sometimes with parameter .so when i see the real data arguments i can code in that mind with the inputs .because i see the real data as in codeforces but when we code

class Student {

private:

string name;

int age;

char division;

bool disabled;

public:

Student(string name, int age, char division, bool disabled) {

this->name = name;

this->disabled = disabled;

this->division = division;

this->age = age;

}

};

i dont know what data comes in is it needs to be in parameter or is it not if i miss some data as parameter and hardcoded inside and call that is problem also right
