Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a property with a get accessor that returns the value of the field.

C Sharp (C#)

private int _age;
public int Age {
    get { return [1]; }
}

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

💡 Hint

Common Mistakes

Returning the property name instead of the field.

Using 'value' inside get accessor.

The get accessor returns the value of the private field _age.

2fill in blank

medium

Complete the code to define a set accessor that assigns the input value to the field.

C Sharp (C#)

private string _name;
public string Name {
    set { [1] = value; }
}

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

A_name

Bthis

Cvalue

DName

💡 Hint

Common Mistakes

Assigning to the property name inside the set accessor causing infinite recursion.

Using 'value' on the left side of assignment.

The set accessor assigns the input value to the private field _name.

3fill in blank

hard

Fix the error in the set accessor to correctly assign the value to the field without recursion.

C Sharp (C#)

private double _price;
public double Price {
    set { [1] = value; }
    get { return _price; }
}

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

A_price

BPrice

Cvalue

Dthis

💡 Hint

Common Mistakes

Assigning to the property name inside set causing stack overflow.

Using 'value' on the left side.

Assigning to _price avoids recursive calls to the property Price.

4fill in blank

hard

Fill both blanks to create a property that only allows setting the field if the value is positive.

C Sharp (C#)

private int _quantity;
public int Quantity {
    get { return _quantity; }
    set {
        if ([1] > 0) {
            [2] = value;
        }
    }
}

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

Avalue

B_quantity

CQuantity

Dthis

💡 Hint

Common Mistakes

Assigning to the property name inside set causing recursion.

Checking the field instead of the input value.

The set accessor checks if the input value is positive and assigns it to the field _quantity.

5fill in blank

hard

Fill all three blanks to create a property that converts the stored name to uppercase when getting and trims whitespace when setting.

C Sharp (C#)

private string _fullName;
public string FullName {
    get { return [1].ToUpper(); }
    set { [2] = value.[3](); }
}

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

A_fullName

BFullName

CTrim

DToLower

Attempts:

💡 Hint

Common Mistakes

Using the property name inside get or set causing recursion.

Using ToLower() instead of Trim() in set.

The get accessor returns the uppercase version of the field _fullName. The set accessor trims whitespace from the input before assigning it to _fullName.
