Which constructor is called by default if a class has multiple constructors in C#?a.The constructor with the 'default' keyword.b.The constructor with the most parameters.c.The constructor that matches the provided arguments.d.The constructor with the fewest parameters.
Solution
The constructor that is called by default when a class has multiple constructors in C# is the one that matches the provided arguments. So, the correct answer is c. The constructor that matches the provided arguments.
Here's a step-by-step explanation:
-
When an instance of a class is created in C#, the runtime system invokes a constructor method to initialize the object.
-
If a class has multiple constructors, the constructor that gets called is determined by the arguments that are passed when the object is instantiated.
-
If no arguments are provided, the default (parameterless) constructor is called. If arguments are provided, the constructor that matches the number and type of the arguments is called.
-
If no matching constructor is found, a compile-time error occurs.
-
The 'default' keyword in C# is not used to specify a default constructor. It is used to return the default value of a type.
-
The number of parameters in a constructor does not determine which constructor is called by default. It's all about the matching of the provided arguments.
So, the constructor that matches the provided arguments (option c) is the one that is called by default when a class has multiple constructors in C#.
