A C++ array can be described as a collection of entities*of the same type*andarranged*contiguously* in memory. C++ inherits its*built-in array* syntax from C, sometimes these are referred to as*C-style* arrays. Uniform initialization syntax can be used to assign the contents of an array at the point it is defined (and**only** at this point). This is called*aggregate initialization* using a*braced initializer* (the equals sign shown below is in fact optional):

A few new things to notice about this program.

A few new things to notice about this program:

* The size of the array called`str[]` is set by an integer constant, and this value is needed twice more in the program where it is accessible as`size(str)`, a compile-time value. An alternative way would be to use a constant or macro at each point the value is needed, and this is the only way to avoid repeated*magic constants* in older versions of C++ which did not provide`std::size()`.

* Now modify the program so that only the last element of the array is printed out, whatever size the array is.
