When we need to call a method or to access a field on an object, we use ________ operator.

& operator

Dot (.) operator

Constructor

New operator

When we create a variable of a class type, we use _______ operator.

New

. operator

We cannot declare a class within another class in C# because this is against the rule of Object-Oriented Programming.

True

False

If no value assigned to a class field, then they will be default numeric values to zero, null for string and false for bool.

True

False

When declaring a class in C#, there is no semicolon (;) to terminate class block.

True

False

Statements inside a class does not need to be terminated with a semicolon (;).

True

False

If we declare a class as a public class, it means that any other class in the project can use it to create objects.

True

False

Class constructors are special methods that fire automatically when a class instance is created.

True

False

If a constructor is not specified, C# generates a default one.

True

False

The default constructor sets any variables to their default type values—numeric values are set to zero, Booleans to false, and reference types (classes) to null.

True

False

Custom constructors can be defined with parameters, just like any other method, and are used to set class variable values at initialization.

True

False

A class can have multiple constructors.

True

False

Constructors does not need to be public.

True

False

Constructors can have return type.

True

False

Constructor name is always the class name.

True

False

Constructor overloading is when we create several constructors for a class.

True

False

For convenience, constructors will often have parameters that share a name with a class variable. In these cases, we use the this keyword to specify which variable belongs to the class. Class’s variable use this, and it makes it distinct from the constructor’s parameter; without the this keyword, the compiler will throw a warning because it won't be able to tell them apart.

True

False

Which of the following is return type of constructor:

Float

Int

No return type

String

Structs are similar to classes in that they are also blueprints for objects you.

True

False

The main difference between classes and structs is that structs are value types; meaning they are passed by value, but classes are reference type.

True

False

Structs are declared in the same way as classes, and can hold fields, methods, and constructors.

True

False

Like classes, any variables and methods belong exclusively to the struct and are accessed by its unique name.

True

False

In structs, variables cannot be initialized with values inside the struct declaration unless they're marked with the static or const modifier.

True

False

In structs, constructors without parameters aren't permitted.

True

False

Structs come with a default constructor that will automatically set all variables to their default values according to their type.

True

False

In c#, you can have classes and structs nested within each other, but this is generally frowned upon because it clutters up the code.

True

False

Classes are best suited for grouping together complex actions and data that will change throughout a program. While, structs are a better choice for simple objects and data that will remain constant for the most part.

True

False

Classes are value types, meaning that they are passed by value; structs are reference types, meaning that they are passed by reference.

True

False

If we have multiple variables storing the same memory reference, a change to one affects them all.

True

False

When a struct object is created, all of its data is stored in its corresponding variable with no references or connections to its memory location. This makes structs useful for creating objects that need to be copied quickly and efficiently, while still retaining their separate identities.

True

False

Structs are easily copied and modified as their separate objects, unlike classes that retain references to an original object.

True

False

OOP focuses on objects rather than pure sequential logic; the data they hold, how they drive action, and, most importantly, how they communicate with each other.

True

False

Inheritance is a powerful way of creating related classes without having to repeat code.

True

False

A child class have member variables and methods from parent class, but able to define its unique data too.

True

False

Child class is the same as derived class.

True

False

Parent class is the same as base class.

True

False

In inheritance, class constructors always belong to their containing class, and they cannot be used from derived classes.

True

False

Any base class members marked with the public, protected, or internal access modifiers are automatically part of the derived class.

True

False

Any base class members marked with the public, protected, or internal access modifiers are automatically part of the derived class; except for constructors.

True

False

It's generally considered best practice to create a new script for different classes instead of adding them to existing ones. This separates your scripts and avoids having too many lines of code in any single file (called a bloated file).

True

False

Which option is correct about the following code?

Character class inherits from Paladin class.

Paladin class inherits from Character class.

Both Paladin class and Character class inherit from MonoBehaviour Class.

Encapsulation defines how accessible an object's variables and methods are to outside code.

True

False

In inheritance, the parent class isn't aware of any of its children, but all children are aware of their parent.

True

False

In inheritance, parent class constructors can be called directly from child constructors with a simple syntax modification.

True

False

In polymorphism, parent classes can mark methods as virtual, meaning that their instructions can be modified by derived classes using the override keyword.

True

False

Polymorphism allows derived classes to keep the structure of their parent class while also having the freedom to tailor actions to fit their specific needs.

True

False

OOP is all about grouping related data and actions into objects—objects that can communicate and act independently from each other.

True

False

Access to class members can be set using access modifiers, just like variables.

True

False

Classes can inherit from other classes, creating trickle-down hierarchies of parent/child relationships.

True

False

Composition means classes can have members of other class or struct types.

True

False

Classes can override any parent methods marked as virtual, allowing them to perform custom actions while retaining the same blueprint.

True

False

Constructor handles the initialization logic inside a class.

True

False

True

False

What are the two categories of lighting in Unity? (Check all that apply)

Lightmap

Real-time lighting

Pre-computed lighting

Precomputed Realtime Global Illumination

Real-time lighting is computed every frame, meaning that any object that passes in its path will cast realistic shadows and generally behave like a real-world light source

True

False

Pre-computed lighting stores the scene's lighting in a texture called a lightmap, which is then applied, or baked, into the scene.

True

False

Pre-computed lighting can significantly slow down our game and cost an exponential amount of computing power, depending on the number of lights in our scene.

True

False

Real-time lighting is static. This means that it doesn't react realistically or change when objects move in the scene.

True

False

Real-time lighting is computationally expensive, while pre-computed lighting saves computing power.

True

False

In addition to real-time lighting and pre-computed lighting, there is also an advanced mixed type of lighting called Precomputed Realtime Global Illumination, which bridges the gap between the real-time and precomputed processes.

True

False

By default, every scene comes with a Directional Light component to act as a main source of illumination.

True

False

Lights can be created in the hierarchy like any other GameObject.

True

False

Lights are objects in Unity, which means they can be positioned, scaled, and rotated to fit our needs.

True

False

Directional lights are great for simulating natural light, such as sunshine. They don't have an actual position in the scene, but their light hits everything as if it's always pointed in the same direction.

True

False

Point lights are essentially floating globes, sending light rays out from a central point in all directions. These have defined positions and intensities in the scene.

True

False

Spotlights send light out in a given direction, but they are locked in by their angle; similar to spotlights or floodlights in the real world.

True

False

Like all GameObjects in Unity, lights have properties that can be adjusted to give a scene a specific ambiance or theme.
