std::all_of 参数说明:(iterator begin, iterator end, condition) 前两个参数是范围, 最后一个是lamda表达式,可以放一个返回bool值的函数 例子 //判断string是不是全部是digitstrings("$1234")boolflag= all_of(s.begin(), s.end(), ::isdigit) ;cout<< flag; std::any_of 用法跟all_of类似,用于判...
类成员函数指针不能作为谓词传递给std::all_of等函数(例如 此处)。然而,有了C ++17的std :: invoke,std :: all_of和类似函数接受成员函数(甚至成员变量)指针就很容易。 更具体地说,以下代码在GCC 9.2上无法编译: #include <algorithm> #include <vector> struct S { bool check() const { return true...
