Question

for c++ answer the following and create the following

(1)Declare a class to hold Employee Data. It must have at least 2 attributes and 1 method in addition to getters/setters for 1 of the 2 attributes. Also, include at least 2 constructors and a destructor. Put the appropriate members in public and private sections. You don't need to write the code to implement the class except for getters and setters which should include the appropriate inline code.

(2)

What is/are the error(s) of the following class declaration?

     #include <iostream>

     using namespace std;

     class TestClass

     {

     private:

         int val;

     public:

         TestClass() { val = 10; }

         TestClass(int x=10) { val = x; }

     };

Answer 1

1)
#include <string>
#include <iostream>
using namespace std;

class Employee {
private:
    string name;
    int age;
public:
    Employee() {}

    Employee(string name, int age) : name(name), age(age) {}

    string getName() const {
        return name;
    }

    void setName(string name) {
        this->name = name;
    }

    int getAge() const {
        return age;
    }

    void setAge(int age) {
        this->age = age;
    }

    void print() {
        cout << "Name: " << name << ", Age: " << age << endl;
    }
};

2)
TestClass default constructor is ambiguous because of (int x=10). to fix it remove =10.
Modified code:
------------------
#include <iostream>

using namespace std;

class TestClass {
private:
    int val;
public:
    TestClass() { val = 10; }

    TestClass(int x) { val = x; }
};
