如何拆分变量以在行间打印出其他内容？

name = "John Doe"
first_name, last_name = name.split()
print("Hello, " + first_name + "! Welcome to our website.")

String name = "John Doe";
String[] parts = name.split(" ");
System.out.println("Hello, " + parts[0] + "! Welcome to our website.");

let name = "John Doe";
let [firstName, lastName] = name.split(" ");
console.log(`Hello, ${firstName}! Welcome to our website.`);

#include <iostream>
#include <string>
using namespace std;

int main() {
  string name = "John Doe";
  string firstName = name.substr(0, name.find(" "));
  cout << "Hello, " << firstName << "! Welcome to our website." << endl;
  return 0;
}
