如何从缓冲读卡器输入字符串？

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入字符串：");
        String inputString = scanner.nextLine();
        System.out.println("您输入的字符串是：" + inputString);
    }
}

#include<iostream>

int main() {
    std::string inputString;
    std::cout << "请输入字符串："<< std::endl;
    std::getline(std::cin, inputString);
    std::cout << "您输入的字符串是："<< inputString<< std::endl;
    return 0;
}

inputString = input("请输入字符串：")
print("您输入的字符串是：" + inputString)

let inputString = prompt("请输入字符串：");
alert("您输入的字符串是：" + inputString);
