Whats the advantage of "class" if a simple program gives the same output..??

Question

i mean the following two programs have same output:
1).
#include <iostream>
using namespace std;

class myClass {
public:
myClass() {
cout <<"Hey";
}
void setName(string x) {
name = x;
}
string getName() {
return name;
}
private:
string name;
};

int main() {
myClass myObj;

return 0;
}
2).
#include<iostream>
using namespace std;
int main()
{
cout<<"Hey";

return 0;
}

Answer 1

Short answer: None. It's redundant. A class represents a blueprint of an object which has its own attributes. The example provided doesn't necessitate the use of classes.
