Slice truncation

You can set the lower and upper limits to intercept slices [lower-bound:upper-bound]. Examples are as follows:

Example

Package main

Import "fmt"

Func main () {

/ * create a slice * /

Numbers: = [] int {0pm 1pm 2je 3je 4J 5pm 6je 7je 8}

PrintSlice (numbers)

/ * print the original slice * /

Fmt.Println ("numbers = =", numbers)

/ * print subslices from index 1 (inclusive) to index 4 (not included) * /

Fmt.Println ("numbers [1:4] =", numbers [1:4])

/ * the default lower limit is 0 percent /

Fmt.Println ("numbers [: 3] =", numbers [: 3])

/ * the default upper limit is len (s) * /

Fmt.Println ("numbers [4:] =", numbers [4:])

Numbers1: = make ([] int,0,5)

PrintSlice (numbers1)

/ * print subslices from index 0 (inclusive) to index 2 (not included) * /

Number2: = numbers [: 2]

PrintSlice (number2)

/ * print subslices from index 2 (inclusive) to index 5 (not included) * /

Number3: = numbers [2:5]

PrintSlice (number3)

}

Func printSlice (x [] int) {

Fmt.Printf ("len=%d cap=%d slice=%v\ n", len (x), cap (x), x)

}

The output result of executing the above code is:

Len=9 cap=9 slice= [0 1 2 3 4 5 6 7 8] numbers = = [0 1 2 3 4 5 6 7 8] numbers [1:4] = [1 23] numbers [: 3] = [0 12] numbers [4:] = [4 56 7 8] len=0 cap=5 slice= [] len=2 cap=9 slice= [0 1] len=3 cap=7 slice= [2 34] Thank you for reading.
