C++:
```cpp
include using namespace std; int main() { for (char a = 'a'; a <= 'z'; a++) { cout << a; } cout << endl; return 0; } ``` Java: ```java public class AlphabetGenerator { public static void main(String[] args) { for (char c = 'A'; c <= 'Z'; c++) { System.out.print(c); } System.out.println(); } } ``` Python: ```python print("abcdefghijklmnopqrstuvwxyz") ``` 或者使用列表推导式: ```python print(''.join([chr(i) for i in range(97, 123)])) ``` JavaScript: ```javascript console.log('abcdefghijklmnopqrstuvwxyz'); ``` C: ```csharp using System; class Program { static void Main() { for (char c = 'a'; c <= 'z'; c++) { Console.Write(c); } Console.WriteLine(); } } ``` 这些示例代码展示了如何在不同的编程语言中生成并打印字母表。你可以根据自己的需要选择合适的编程语言和实现方式。
