这是代码，可以放在c++里执行一下，就知道了↓

#include <iostream>

int main() {
    std::cout << "=== Compiler Diagnostic ===\n";
    
    // 1. 标准版本
    std::cout << "C++ standard: ";
    #if __cplusplus == 199711L
        std::cout << "C++98/03\n";
    #elif __cplusplus == 201103L
        std::cout << "C++11\n";
    #elif __cplusplus == 201402L
        std::cout << "C++14\n";
    #elif __cplusplus == 201703L
        std::cout << "C++17\n";
    #elif __cplusplus == 202002L
        std::cout << "C++20\n";
    #else
        std::cout << "Unknown: " << __cplusplus << "\n";
    #endif
    
    // 2. 检查特定功能支持
    std::cout << "Features:\n";
    
    #if __cplusplus >= 201103L
        std::cout << "  ? C++11 features enabled\n";
        #ifdef __cpp_range_based_for
            std::cout << "  ? Range-based for loops\n";
        #endif
        #ifdef __cpp_initializer_lists
            std::cout << "  ? Initializer lists\n";
        #endif
        #ifdef __cpp_auto_type
            std::cout << "  ? auto keyword\n";
        #endif
    #else
        std::cout << "  ? C++11 features NOT enabled\n";
    #endif
    
    // 3. 编译器信息
    std::cout << "\nCompiler info:\n";
    #ifdef __GNUC__
        std::cout << "  GCC version: " << __GNUC__ << "." 
                  << __GNUC_MINOR__ << "." << __GNUC_PATCHLEVEL__ << "\n";
    #endif
    #ifdef _MSC_VER
        std::cout << "  MSVC version: " << _MSC_VER << "\n";
    #endif
    
    return 0;
}
