What is the main difference between structured programming and object-oriented programming?
Structured programming and object-oriented programming are essentially the same, with only minor differences in syntax and terminology.
Structured programming focuses on the sequence of actions to be performed, while object-oriented programming emphasizes the objects involved in the actions.
Structured programming is based on objects that encapsulate both data and behavior, while object-oriented programming is based on a top-down approach where the program is divided into smaller, manageable functions or procedures.
What is the main difference between a static class and a non-static class?
A static class can't be instantiated and it contains only static members.
A static class can't contain static methods, fields, properties, or events.
A static class can be instantiated using the 'new' operator.
What is the purpose of using the partial keyword in class definitions?
It allows a class to inherit from multiple base classes.
It enables the splitting of a class definition over two or more source files.
It makes a class abstract, meaning it can't be instantiated directly.
What happens when named and optional arguments are used in a method?
The arguments are evaluated in the order in which they appear in the parameter list, not the argument list.
The arguments are evaluated in the order in which they appear in the argument list, not the parameter list, and they allow supplying arguments for selected parameters.
Named and optional parameters do not allow supplying arguments for selected parameters.
What is the purpose of a copy constructor in C#?
It allows you to create a new object by copying the values of an existing object's methods.
It allows you to create a new object by copying the values of an existing object's properties.
It allows you to assign values to any accessible fields or properties of an object at creation time without having to invoke a constructor followed by lines of assignment statements.
What is the role of a finalizer in a class in C#?
Finalizers are used to allocate memory for a class instance.
Finalizers are used to perform any necessary final clean-up when a class instance is being collected by the garbage collector.
Finalizers can be called explicitly to perform specific actions.
What is the primary purpose of implementing classes in C# applications?
To increase the execution speed of the application
To create a visual representation of the application
To encapsulate data and behavior into objects
