You want to create a class Book with a public string field Title and a constructor that sets Title. Which is the correct declaration?
Apublic class Book {
public string Title;
public Book(string title) {
Title = title;
}
}
Bclass Book {
string Title;
void Book(string title) {
Title = title;
}
}
Cpublic class Book {
private string Title;
public void Book(string title) {
Title = title;
}
}
Dpublic class Book {
public string Title;
public void Book(string title) {
Title = title;
}
}
Step-by-Step Solution
Solution:
Step 1: Check field and constructor declaration
The field Title is public, and the constructor has the same name as the class without a return type.
Step 2: Identify correct constructor syntax
public class Book {
public string Title;
public Book(string title) {
Title = title;
}
} correctly declares a public constructor Book(string title) that sets the field.
Final Answer:
public class Book {
public string Title;
public Book(string title) {
Title = title;
}
} -> Option A
Quick Check:
Constructor name = class name, no return type [OK]
Quick Trick:Constructor name matches class name, no return type [OK]
