Constructs new numeric array from various sources.

1) Default constructor. Constructs an empty numeric array.

2) Constructs a numeric array with count copies of value-initialized elements.

3) Constructs a numeric array with count copies of val.

4) Constructs a numeric array with copies of count values from an array pointed to by vals. If this array contains less than count values, the behavior is undefined.

5) Copy constructor. Constructs the numeric array with the copy of the contents of other.

6) Move constructor. Constructs the container with the contents of other using move semantics.

7-10) Converting constructor. Convert the corresponding data structure to a valarray.

11) Constructs the numeric array with the contents of the initializer list il.

Parameters

count	-	the number of elements to construct
val	-	the value to initialize the elements with
vals	-	pointer to a C array to use as source to initialize the contents
other	-	another numeric array to use as source to initialize the contents
il	-	initializer list to initialize the elements with
