Solve it, please.

Question

How can this code work??
#include <iostream>
#include <string>
using namespace std;
class Hello {
public:
void Celeb(string x) {
cout<< x << endl;
string x = "Very thanks for 200 followers!"
}
public:
string x;
};
int main() {
Hello obj;
obj();
return 0;
};

Answer 1

you have to call the method with the . (dot) operator. No clue why people downvoted AJ || ANANT. He's right. You use the object to reference the method. Instead of obj() , you would write obj.Celeb(); but you'd have to pass a string parameter with it. Not sure what you're trying to do, but to access a class method you must use the . operator in conjunction with the object.

Example:

class Student
{

private:
testScore = 0;

public:
void setScore(int x)
{
testScore = x;
}
}

int main()
{
Student student_object;

student_object.setScore(100);

return 0;
}

Answer 2

Stephen Matthew I dont know why. I think they know better than me who downvoted.

Answer 3

You created object but not calling method.

Answer 4

Yes, what AJ said. If you create a method with a parameter, you must pass a parameter with it when you call it.

Answer 5

Ilove Bts Because you didn't pass the parameter in setHello() function from outside.

Pass parameter in setHello function. Then it will work..

#include <iostream>
#include <string>
using namespace std;
class Hello{
private:
string fr_hel;
string se_hel;

public:
void setHello(string t)
{
cout << t << endl;
}

};
int main() {
Hello obj;
obj.setHello("AJ");
return 0;
};

It will print AJ

Answer 6
