Go language provides inbuilt support to implement conversions to and from string representations of basic data types by strconv Package. This package provides an AppendBool() function which is used to append bool(i.e, true or false) according to the value of num2 to num1 and returns the extended buffer as shown in the syntax. To access AppendBool() function you need to import strconv Package in your program.
Syntax:
func AppendBool(num1 []byte, num2 bool) []byte
Example 1:
// Golang program to illustrate // strconv.AppendBool() Function package main import ( "fmt"
"strconv"
) func main() { // Using AppendBool() function
val := []byte( "Is Bool: " )
val = strconv.AppendBool(val, true )
fmt.Println(string(val))
} |
Output:
Is Bool: true
Example 2:
// Golang program to illustrate // strconv.AppendBool() Function package main import ( "fmt"
"strconv"
) func main() { // Using AppendBool() function
val := []byte( "Append Bool:" )
fmt.Println(string(val))
fmt.Println( "Length(Before): " , len(val))
fmt.Println( "Capacity(Before): " , cap(val))
val = strconv.AppendBool(val, true )
fmt.Println(string(val))
fmt.Println( "Length(After): " , len(val))
fmt.Println( "Capacity(After): " , cap(val))
} |
Output:
Append Bool: Length(Before): 12 Capacity(Before): 12 Append Bool:true Length(After): 16 Capacity(After): 32
