=operators differs from string comparison using the xref:System.String.CompareTo%2A?displayProperty=nameWithType and xref:System.String.Compare(System.String,System.String)?displayProperty=nameWithType) methods. They all perform a case-sensitive comparison. However, while the tests for equality perform...
Visual Studio 2019 correctly raises warning C4244. To avoid the warning, you can initialize the std::string as shown in this example:C++ Αντιγραφή std::wstring ws = L"Hello world"; std::string out; for (wchar_t ch : ws) { out.push_back(static_cast<char>(ch)); }...
Often it isuseful to know whether astringis empty. One way we could do so would be to comparesizewith 0: 了解string对象是否空是有用的。一种方法是将size与0进行比较: if (st.size() == 0)// ok: empty In thiscase, we don't really need to know how many characters are in thestring...
