Type類型的對象必須是相等可比較的。 在物件集合上定義的operator!=必須符合等價關聯的數學屬性,才能進行此作業。 所有內建的數字和指標類型皆符合這項需求。 範例 C++ // functional_not_equal_to.cpp// compile with: /EHsc#include<vector>#include<functional>#include<algorithm>#include<iostream>usingnamespace...
std::not_equal_to Defined in header<functional> template<classT> structnot_equal_to; (until C++14) template<classT=void> structnot_equal_to; (since C++14) Function object for performing comparisons. Unless specialised, invokesoperator!=on typeT. ...

C++ Multimap Not Equal Operator - Learn about the not equal operator for C++ multimaps, including syntax, examples, and usage.
您使用3个参数调用std::equal,其中https://en.cppreference.com/w/cpp/algorithm/equal表示: 如果范围[first1,last1]等于范围[first2,first2+(last1-first1)),则返回true,否则返回false 在您的案例中,这将导致未定义的行为 将std::equal与4个参数一起使用: std::equal(a.begin(), a.end(), b.begin...
struct not_equal_to<void> { template<class Type1, class Type2> auto operator()(Type1&& Left, Type2&& Right) const -> decltype(std::forward<Type1>(Left) != std::forward<Type2>(Right)); }; Parameters Type, Type1, Type2 Any type that supports an operator!= that takes operands of...
so I was messing around with Cpp and I wanted to ask for user input and if the statement is the same as I want, then it would run a function. but it doesn't work as expe
