iostream is a C++ thing, not C. You might get more help if you re-tag your question appropriately.
iostream 是 C++ 的东西，而不是 C。如果您适当地重新标记您的问题，您可能会获得更多帮助。

IIRC, /usr/local/lib ... Try adding -L/usr/local/lib to your GCC build options. Although the stdc++ libraries shouldbe in your linker path already. Compiler errors usually indicate missing headers / syntax error while linker errors indicate missing binary blobbage.
IIRC, /usr/local/lib ... 尝试将 -L/usr/local/lib 添加到您的 GCC 构建选项中。尽管 stdc++ 库应该已经在您的链接器路径中。编译器错误通常表示缺少头文件/语法错误，而链接器错误表示缺少二进制 blobbage。

for me it is under the Xcode library directory: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/.
对我来说，它在 Xcode 库目录下：/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/。
