Some questions about the source code #222
Description
You use a lot of std namespaces in your cpp source files, but to my surprise, your project doesn't have library functions like strcmp in std namespaces, while I created a new test file, which can be called directly by std::strcmp. So I'm so confusing, and I'm even more surprised that exit() also reports an error.
What's more, I can't open some of these project,Why?
