Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a record struct named Point with two integer properties X and Y.

C Sharp (C#)

public [1] Point(int X, int Y);

💡 Hint

Common Mistakes

Using 'class' or 'record class' instead of 'record struct'.

Using just 'struct' which is not a record struct.

The keyword record struct declares a record struct in C# which is a value type with built-in value equality.

Complete the code to create a new Point record struct instance with X=5 and Y=10.

C Sharp (C#)

var p = new Point([1], 10);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the property name 'X' instead of the value 5.

Using 10 for the first parameter instead of the second.

When creating a new instance, you provide the values for the parameters. Here, X is 5.

Fix the error in the code to correctly compare two Point record structs for equality.

C Sharp (C#)

bool areEqual = p1 [1] p2;

Drag options to blanks, or click blank then click option'

Aequals

B==

C!=

D=

💡 Hint

Common Mistakes

Using '=' which is assignment, not comparison.

Using 'equals' which is not a valid operator in C#.

Record structs support value equality with the == operator.

Fill both blanks to declare a record struct named Rectangle with properties Width and Height.

C Sharp (C#)

public [1] Rectangle(int [2], int Height);

Drag options to blanks, or click blank then click option'

Arecord struct

Bclass

CWidth

DHeight

💡 Hint

Common Mistakes

Using 'class' instead of 'record struct'.

Using 'Height' instead of 'Width' for the first parameter.

The declaration uses 'record struct' and the first parameter name is 'Width'.

5fill in blank

hard

Fill all three blanks to create a new Rectangle instance with Width=15 and Height=25, then check if Width is greater than 10.

C Sharp (C#)

var rect = new Rectangle([1], [2]);
bool isWide = rect.Width [3] 10;

Drag options to blanks, or click blank then click option'

A15

B25

C>

D<

💡 Hint

Common Mistakes

Swapping Width and Height values.

Using '<' instead of '>' for the comparison.

The Rectangle is created with Width=15 and Height=25. The comparison checks if Width is greater than 10.
