Go Programming Language Array
Go Programming Language Array
In Go programming, Array object is used for collection manipulation.
Define array variable
// one dimensional array var numbers[4] int var name[4] string // two dimentsional array var matrix[3][3] int
Go Array Example
This Go code is used to explain how to declare the array, inserting data in array and reading array data to print.
package main
import "fmt"
func main() {
var numbers[4] int
var name[4] string
fmt.Println("Inserting array data")
// insert array data
for i:=0;i<4;i++ {
numbers[i] = i+1
name[i] = fmt.Sprintf("Test Name%d", i)
}
fmt.Println("Print array data")
// Prints array data
for i:=0;i<4;i++ {
fmt.Printf("number %d: %d\n", i, numbers[i])
fmt.Printf("name %d: %s\n", i, name[i])
}
}
Output:
$ go build array.go $ ./array Inserting array data Print array data number 0: 1 name 0: Test Name0 number 1: 2 name 1: Test Name1 number 2: 3 name 2: Test Name2 number 3: 4 name 3: Test Name3
Go Two Dimensional Array
Syntax:var Matrix[3][3] int
Go Two Dimensional Array Example
Below code explains how to declare two dimensional array, insert values and reading array values.
package main
import "fmt"
func main() {
var matrix[3][3] int
fmt.Println("Inserting array data")
// insert array data
for i:=0;i<3;i++ {
for j:=0;j<3;j++ {
matrix[i][j] = i*j
}
}
fmt.Println("Print array data")
// Prints array data
for i:=0;i<3;i++ {
for j:=0;j<3;j++ {
fmt.Printf("%d",matrix[i][j])
if j!=2 {
fmt.Printf("\t")
}
}
fmt.Printf("\n")
}
}
Output:
$ go build array.go $ ./array Inserting array data Print array data 0 0 0 0 1 2 0 2 4« Previous Next »
