C++ Class Constructor Data Passing

Question

I have a quiz that's due soon and I'm having a tough time with one question in particular. The question is:

Implement the constructor for the class called "SimpleMath". The constructor takes two integer parameters; "var1" and "var2". The constructor is to store the value that was passed into "var1" into the private integer member variable "m_value1" and the value that was passed into "var2" into the private integer member variable "m_value2"

This is my code;

class SimpleMath
{

public:

    SimpleMath(int var1, int var2);

    int getVar1() const
    {
        return m_value1;
    } 
    int getVar2() const
    {
        return m_value2;
    } 

private:
   int m_value1;
   int m_value2;

};

I was wondering if someone can verify that it is or is not correct. If it's not I'd appreciate any help you can offer. Thank you in advance.

Answer 1

Please implement the constructor in your example. Below example demonstrates how to do so:

class SimpleMath
{

public:

    SimpleMath(int var1, int var2) : m_value1(var1), m_value2(var2) {};

    int getVar1() const
    {
        return m_value1;
    } 
    int getVar2() const
    {
        return m_value2;
    } 

private:
   int m_value1;
   int m_value2;

};

Answer 2

it's correct but you forgot to show how you store value, you juste define function here . . .

SimpleMath(int var1, int var2)
{
 //somme stuff
}
