# Golang Program to Print an Identity Matrix

Go ProgrammingServer Side ProgrammingProgramming

The steps to print an identity matrix using Golang is as follows :

• Take a value from the user and store it in a variable, n.
• Use two for loops where the value of j ranges between the values of 0 and n-1 and the value of i also ranges between 0 and n-1.
• Print the value of 1 when i is equal to j, and 0 otherwise.

### Case 1:

Enter a number: 4
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1

### Case 2:

Enter a number: 5
1 0 0 0 0
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1

## Example

Live Demo

package main
import "fmt"
func main(){
var n int
fmt.Print("Enter a number: ")
fmt.Scanf("%d", &n)
for i:=0; i<n; i++{
for j:=0; j<n; j++{
if i == j{
fmt.Print("1 ")
} else {
fmt.Printf("0 ")
}
}
fmt.Println()
}
}

## Output

Enter a number: 5
1 0 0 0 0
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1
