For C++

Write a code fragment that allocates an array of double of size 10 using new and initializes a pointer. Include the declaration of the pointer. Write the statement that frees the memory allocated above

Also, I am reviewing the definition of a default assignment operator. for C++.

I am told that "It assigns each data member fr simple data types." does this mean that class defined objects do not work at all unles the = is overloaded? By simple data types does this mean already reconized types such as int floats and doubles?
