好的，以下是示例代码： ```c++ #include <iostream> int main() { // 打印基本类型的大小 std::cout << "Size of char: " << sizeof(char) << " bytes" << std::endl; std::cout << "Size of short: " << sizeof(short) << " bytes" << std::endl; std::cout << "Size of int: " << sizeof(int) << " bytes" << std::endl; std::cout << "Size of long: " << sizeof(long) << " bytes" << std::endl; std::cout << "Size of long long: " << sizeof(long long) << " bytes" << std::endl; std::cout << "Size of float: " << sizeof(float) << " bytes" << std::endl; std::cout << "Size of double: " << sizeof(double) << " bytes" << std::endl; std::cout << "Size of long double: " << sizeof(long double) << " bytes" << std::endl; // 打印指针类型的大小 std::cout << "Size of int*: " << sizeof(int*) << " bytes" << std::endl; std::cout << "Size of char*: " << sizeof(char*) << " bytes" << std::endl; std::cout << "Size of void*: " << sizeof(void*) << " bytes" << std::endl; // 打印自定义枚举类型的大小 enum Color { RED, GREEN, BLUE }; std::cout << "Size of Color enum: " << sizeof(Color) << " bytes" << std::endl; return 0; } ``` 输出结果： ``` Size of char: 1 bytes Size of short: 2 bytes Size of int: 4 bytes Size of long: 8 bytes Size of long long: 8 bytes Size of float: 4 bytes Size of double: 8 bytes Size of long double: 16 bytes Size of int*: 8 bytes Size of char*: 8 bytes Size of void*: 8 bytes Size of Color enum: 4 bytes ```
