In Go+, an array is a numbered sequence of elements of a specific length.
Declaration of a one-dimensional array
Here we create an array
a that will hold exactly
ints. The type of elements and length are both
part of the array’s type. By default an array is
zero-valued, which for
We can set a value at an index using the
array[index] = value syntax, and get a value with
len returns the length of an array.
Use this syntax to declare and initialize an array in one line.
If you don’t want to write the length of the array, you can use this method and let the compiler calculate the length of the array itself.
Declaration of multidimensional arrays
Array types are one-dimensional, but you can compose types to build multi-dimensional data structures.
If you need to declare more dimensions, you can extend them yourself, such as declaring a 2*2*3 three-dimensional array
If you do not declare the contents of the array in Go+, the compiler automatically initializes the array to 0; For an array of type bool, the initial value is false.
For more array value types, Go+ supports strings, integers, floats, Booleans, etc. See this chapter for details:
