Go Arrays
Introduction
Arrays are specific data type, representing an ordered collection of elements of another type.
In Go, Arrays can be simple (sometime called "lists") or multi-dimensional (like for example a 2-dimentions arrays is representing a ordered collection of arrays, that contains elements)
Syntax
- var variableName [5]ArrayType // Declaring an array of size 5.
- var variableName [2][3]ArrayType = { {Value1, Value2, Value3}, {Value4, Value5, Value6} } // Declaring a multidimensional array
- variableName := [...]ArrayType {Value1, Value2, Value3} // Declare an array of size 3 (The compiler will count the array elements to define the size)
- arrayName[2] // Getting the value by index.
- arrayName[5] = 0 // Setting the value at index.
- arrayName[0] // First value of the Array
- arrayName[ len(arrayName)-1 ] // Last value of the Array
