Initialization #3

Open randomwangran opened 6 years ago

You can give a default initialization value directly:

    int m_length = 0;
    int *m_array = nullptr;

Those two pieces of code are essentially equal to each other because of what I wrote in my constructor:

IntArray(int size = 0) : m_size(size) 
{
    int *m_array = new int[m_size];
}
