1fill in blank

easy

Complete the code to declare a getter method for the private member age.

C++

class Person {
private:
    int age;
public:
    int getAge() const {
        return [1];
    }
};

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

💡 Hint

Common Mistakes

Using parentheses after the variable name like a function call.

Using incorrect capitalization.

The getter method should return the private member variable age directly.

2fill in blank

medium

Complete the code to declare a setter method for the private member age.

C++

class Person {
private:
    int age;
public:
    void setAge(int [1]) {
        age = value;
    }
};

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

💡 Hint

Common Mistakes

Using a parameter name different from the one used in the assignment.

Using the same name as the member variable without this->.

The setter method parameter should be named value to match the assignment inside the method.

3fill in blank

hard

Fix the error in the setter method to correctly assign the parameter to the member variable.

C++

class Person {
private:
    int age;
public:
    void setAge(int value) {
        [1] = value;
    }
};

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

CsetAge

Dthis->age

💡 Hint

Common Mistakes

Assigning the parameter to itself.

Using the member variable name without this-> when parameter name is the same.

To avoid ambiguity, use this->age to refer to the member variable inside the setter.

4fill in blank

hard

Fill both blanks to create a getter and setter for the private member score.

C++

class Game {
private:
    int score;
public:
    int [1]() const {
        return score;
    }
    void [2](int value) {
        score = value;
    }
};

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

AgetScore

BsetScore

Cscore

DupdateScore

💡 Hint

Common Mistakes

Using the same name for both getter and setter.

Using incorrect method names that don't follow conventions.

The getter is conventionally named getScore and the setter setScore.

5fill in blank

hard

Fill all three blanks to create a class with private member level and its getter and setter methods.

C++

class Player {
private:
    int [1];
public:
    int [2]() const {
        return [1];
    }
    void [3](int value) {
        [1] = value;
    }
};

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

Alevel

BgetLevel

CsetLevel

Dscore

💡 Hint

Common Mistakes

Using inconsistent variable names.

Not matching getter and setter names with the variable.

The private member is level, the getter is getLevel, and the setter is setLevel.
