Right way to initialize a pointer in a constructor

Question

I have the following exercise:

Add code to make it run properly.

class MyInt
{
public:

private:
    int* MyValue;
}

int main(int argc,char** a         


        

Answer 1

Another way:

MyInt(int x) : MyValue(new int(x)) {}

This doesn't require the additional member. However, you have to make sure that you deallocate the memory in the destructor.

~MyInt() { delete MyValue; }
