以下是使用 C++在 Visual Studio 2022 中编译并输出 `a` 为 `3.000000` ，`b` 为 `4.000000` ，`c` 为 `5.000000` 的示例代码： ```cpp #include <iostream> int main() { double a = 3.000000; double b = 4.000000; double c = 5.000000; std::cout << "a = " << a << std::endl; std::cout << "b = " << b << std::endl; std::cout << "c = " << c << std::endl; return 0; } ``` 如果您使用的是 C#，以下是示例代码： ```csharp using System; class Program { static void Main() { double a = 3.000000; double b = 4.000000; double c = 5.000000; Console.WriteLine("a = " + a); Console.WriteLine("b = " + b); Console.WriteLine("c = " + c); } } ``` [2024-10-20 21:03:13 | AI写代码神器 | 311点数解答]
