go length of array code example
Example 1: golang size of slice
// Create an exmaple array
array := []int{1, 2, 3, 4, 5}
// Print number of items
fmt.Println("First Length:", len(array))
Example 2: how to get the length of an array in go
array:=[]int {1,2,3,4}
len(array)
Example 3: go arrays
var a [10]int // declare an int array with length 10. Array length is part of the type!
a[3] = 42 // set elements
i := a[3] // read elements
// declare and initialize
var a = [2]int{1, 2}
a := [2]int{1, 2} //shorthand
a := [...]int{1, 2} // elipsis -> Compiler figures out array length
