As a reminder, the name of a variable (or function, type, or other kind of item) is called an identifier. C++ gives you a lot of flexibility to name identifiers as you wish. However, there are a few rules that must be followed when naming identifiers: The identifier can not be a keyword. Keywords are reserved.

How parameters and arguments work together. When a function is called, all of the parameters of the function are created as variables, and the value of each of the arguments is copied into the matching parameter (using copy initialization). This process is called pass by value. Function parameters that utilize pass by value are called value ...Synchrony Bank is not as well known as Chase or American Express, but they offer tons of popular store brand credit cards.

Instead of deep copying the source object (a) into the implicit object, we simply move (steal) the source object’s resources. This involves shallow copying the source pointer into the implicit object, then setting the source pointer to null.
