在不同的编程语言中,实现输入0退出程序的方法有所不同。以下是一些常见编程语言中实现该功能的示例代码:
C++:
```cpp
include using namespace std; int main() { int n; while (cin >> n) { if (n == 0) { return 0; } else if (n % 4 == 2) { cout << "yes" << endl; } else { cout << "no" << endl; } } return 0; } ``` Python: ```python while True: input_num = int(input("请输入一个数字(按0退出):")) if input_num == 0: print("程序已退出!") break else: print("您输入的数字是:", input_num) ``` Java: ```java import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); while (true) { int n = scanner.nextInt(); if (n == 0) { System.out.println("程序已退出!"); break; } else if (n % 4 == 2) { System.out.println("yes"); } else { System.out.println("no"); } } scanner.close(); } } ``` C: ```c include int main() { int n; while (scanf("%d", &n) == 1) { if (n == 0) { break; } else if (n % 4 == 2) { printf("yes "); } else { printf("no "); } } return 0; } ``` JavaScript (Node.js): ```javascript const readline = require('readline'); const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); rl.on('line', (input) => { const num = parseInt(input, 10); if (num === 0) { rl.close(); console.log('程序已退出!'); } else { console.log(`您输入的数字是: ${num}`); } }); ``` 这些示例代码展示了如何在不同的编程语言中实现输入0退出程序的功能。你可以根据自己的需求选择合适的编程语言和实现方式。
