Go 语言提供内置支持,以通过strconv Package实现基本数据类型的字符串表示的转换。这个包提供了一个CanBackquote()函数,用于检查字符串str 是否可以不变地表示为单行反引号字符串,除了制表符之外没有控制字符。要访问 CanBackquote()函数,您需要借助 import 关键字在程序中导入 strconv 包。
句法:
func CanBackquote(str string) bool
参数:该函数接受一个字符串类型的参数,即str。
返回值:如果字符串str 可以不变地表示为单行反引号字符串 ,则此函数返回 true ,否则返回 false 。
让我们在给定示例的帮助下讨论这个概念:
示例 1:
// Golang program to illustrate
// strconv.CanBackquote() Function
package main
import (
"fmt"
"strconv"
)
func main() {
// Checking whether the given
// string can be represented
// unchanged as a single-line
// backquoted string
// Using CanBackquote() function
fmt.Println(strconv.CanBackquote("Welcome to GeeksforGeeks"))
fmt.Println(strconv.CanBackquote("`Welcome to GeeksforGeeks`"))
fmt.Println(strconv.CanBackquote(`"Welcome to GeeksforGeeks"`))
}
输出:
true
false
true
示例 2:
// Golang program to illustrate
// strconv.CanBackquote() Function
package main
import (
"fmt"
"strconv"
)
// Main function
func main() {
// Checking whether the given
// string can be represented
// unchanged as a single-line
// backquoted string
// Using CanBackquote() function
res := strconv.CanBackquote("Welcome to GeeksforGeeks")
if res == true {
fmt.Println("The given string is unchanged "+
"single-line backquoted string.")
} else {
fmt.Println("The given string is a "+
"changeable single-line backquoted string.")
}
}
输出:
The given string is unchanged single-line backquoted string.
