Understanding the Difference Between reserve() and resize()

The capacity of a vector<> can be resized by calling either reserve() or resize(). These member functions differ in two respects. Unlike resize(), which allocates memory and initializes it with a default value, reserve() only allocates raw memory without initialization. In addition, reserve() does not change the size of a vector; it only changes the vector's capacity.
