cpp loop through object

#include <iostream>
#include <vector>

class MyClass {
public:
    int data;
    MyClass(int d) : data(d) {}
};

int main() {
    std::vector<MyClass> myVec;

    myVec.push_back(MyClass(1));
    myVec.push_back(MyClass(2));
    myVec.push_back(MyClass(3));

    for (auto& obj : myVec) {
        std::cout << obj.data << std::endl;
    }

    return 0;
}

• Including necessary libraries: iostream and vector.
• Declaring a class named MyClass with a public int member variable data.
• Defining a constructor for MyClass that initializes the data member with the provided argument.
• In the main() function:
• Declaring a vector named myVec that stores objects of type MyClass.
• Adding three MyClass objects with data values 1, 2, and 3 into the myVec vector using push_back().
• Entering a for loop that iterates through each object (denoted by auto& obj) in the myVec vector.
• Inside the loop, printing the data member of each object using std::cout.
• Finally, returning 0 to indicate successful program execution.
