What is the correct way to create an object? (Click all that apply)

For the following definition:

```cpp
struct Person {
int age;
string name;
};
```

Options:
A. `Person ed("Ed", 21);`
B. `Person ed(21, "Ed");`
C. `Person ed; ed.name = "Ed"; ed.age = 21;`
D. `Person ed = new Person; ed.name = "Ed"; ed.age = 21;`
E. `Person* ed = new Person; ed->name = "Ed"; ed->age = 21;`
F. `Person ed; ed.age = 21; ed.name = "Ed";`

Answer :

Final answer:

The correct ways to create a Person object based on the provided struct are using direct list initialization or declaring an object and then initializing fields separately. The use of 'new' and arrow operator is not applicable.

Explanation:

The correct way to create an object in many programming languages, including C++ and similar syntax-based languages, based on the provided struct definition for a Person, involves declaring an object and then initializing its fields. Given the definition struct Person { int age; string name; }, the correct object declaration and initialization options are:

  • Person ed; followed by ed.name = "Ed"; ed.age = 21;
  • Person ed = { "Ed", 21 }; which uses list initialization (provided the programming language supports this syntax).

Other syntax mentioned in the question, such as using a new keyword or arrow operator (->), is not applicable for structures in languages like C++. In languages like C#, the new keyword is used to create objects, but the syntax would require a constructor which is not provided in the example.
