How to do it...

We will create a custom class that allocates a specified amount of memory and statically allocates two instances of the class. Follow these steps:

1. In your working directory, that is, ~/test, create a subdirectory called static.
2. Use your favorite text editor to create a file called static.cpp in the static subdirectory.
3. Let's define a class named Complex. Put its private field and the constructor in the static.cpp file:

#include <iostream>#include <stdint.h>  class Complex {  char* ptr;  public:    Complex(size_t size) noexcept {      try {        ptr = new(std::nothrow) char[size];        if (ptr) {          std::cout << "Successfully allocated "                    << size << " bytes" << std::endl;        } else {          std::cout << "Failed to allocate " << size << " bytes" << std::endl; ...
