How to Convert a zero terminated byte array to string in Golang?

Here the task is to Convert a zero-terminated byte array to string in Golang, you can use the following method:

1. The string() Function: It is used to convert a zero-terminated byte array to string.

Syntax:

str := string(byteArray[:])

Example:

// Go program to illustrate how to  
// convert a zero terminated byte 
// array to string. 
   
package main 
   
import ( 
        "fmt"
) 
   
func main() { 
       
       
    // zero terminated byte 
    // array 
     arr := [20]byte{'a', 'b', 'c' , '1', '2', '3'} 
        
    // printing the array 
     fmt.Println("Array: ", arr) 
        
     // convert a zero terminated 
     // byte array to string 
     // using string() method 
     str := string(arr[:]) 
        
     // printing the converting 
     // string 
     fmt.Println("Conversion to string: ", str)   
} 

Output:

Array:  [97 98 99 49 50 51 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
Conversion to string:  abc123

2. The Sprintf() Function: It is also used to convert a zero-terminated byte array to string. But the performance is less than the previous function.

Syntax:

str := fmt.Sprintf("%s", byteArray)

Example:

// Go program to illustrate how to  
// convert a zero terminated byte 
// array to string. 
   
package main 
   
import ( 
        "fmt"
) 
   
func main() { 
       
       
    // zero terminated byte 
    // array 
     arr := [20]byte{'a', 'b', 'c' , '1', '2', '3'} 
        
    // printing the array 
     fmt.Println("Array: ", arr) 
        
     // convert a zero terminated 
     // byte array to string 
     // using Sprintf() method 
     str := fmt.Sprintf("%s", arr) 
        
     // printing the converting 
     // string 
     fmt.Println("Conversion to string: ", str) 
       
} 

Output:

Array:  [97 98 99 49 50 51 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
Conversion to string:  abc123
