例如,多載 func(const pair<int, int>&) 和func(const pair<string, string>&),以及使用 pair<const char *, const char *> 呼叫func() 時,便會使用這項變更進行編譯。 但此變更會破壞需要積極執行 pair 轉換的程式碼。 一般可以藉由明確執行轉換的其中一部分來修正這類程式碼,例如將 make_pair(static_...
First, <string> no longer includes <iterator>. Second, <tuple> now declares std::array without including all of <array>, which can break code through the following combination of code constructs: your code has a variable named "array", and you have a using-directive "using namespace std;...

25 Answers Sorted by: 200 You can use the strtok() function to split a string (and specify the delimiter to use). Note that strtok() will modify the string passed into it. If the original string is required elsewhere make a copy of it and pass the copy to strtok(). EDIT: Example...
例如,重载 func(const pair<int, int>&) 和func(const pair<string, string>&),并使用 pair<const char *, const char *> 调用func(),将使用此更改进行编译。 但是,此更改会中断依赖主动对转换的代码。 通常可以通过显式执行部分转换来修复这些代码,例如,将 make_pair(static_cast<B>(a), x) 传递给...
