编译器报错:main.cpp:66:6: error: specializing member ‘Array<Student>::Sort’ requires ‘template<>’ syntax

时间: 2023-12-21 14:03:42 浏览: 24
这个错误是因为你在实现模板类的特化时没有使用正确的语法。当你特化模板类的成员时,你需要使用`template<>`语法来明确你正在特化一个模板。在你的代码中,你需要在特化`Array<Student>`类的`Sort`函数之前添加`template<>`,以明确你正在特化模板类的成员。例如: ```cpp template<> void Array<Student>::Sort() { // 实现特化版本的 Sort 函数 } ``` 这应该可以解决这个问题。如果你还有其他问题,请让我知道。

/var/www/data/solutions/214938/main.cpp:40:6: error: specializing member 'shuzu<std::basic_string<char> >::paixu' requires 'template<>' syntax什么意思

这个错误是指你在对 `shuzu<std::basic_string<char>>` 的 `paixu` 成员进行特化时,没有使用正确的语法。 针对一个类模板进行特化时,需要使用以下语法: ```cpp template <> class ClassName<Type> { /* ... */ }; ``` 也就是需要在 `template <>` 后面指定类名和类型参数,并在大括号中提供特化的定义。如果你没有使用这个语法,编译器会认为你的代码有语法错误,从而报出这个错误信息。 请检查你的代码,确保特化语法正确。

E:\数据结构实验\树\树.cpp|38|error: specializing member 'BiTree<int>::countleaf' requires 'template<>' syntax|

这个错误提示是因为你在定义 `countleaf` 函数的时候没有使用模板特化语法。根据错误提示,你需要使用下面的语法: ```cpp template<> int BiTree<int>::countleaf(BiTree<int>::Node* p) const { // 函数实现 } ``` 注意,这里的 `template<>` 表示这是一个模板特化,后面的 `<int>` 表示特化的类型是 `int`。

用c++解决Several currency exchange points are working in our city. Let us suppose that each point specializes in two particular currencies and performs exchange operations only with these currencies. There can be several points specializing in the same pair of currencies. Each point has its own exchange rates, exchange rate of A to B is the quantity of B you get for 1A. Also each exchange point has some commission, the sum you have to pay for your exchange operation. Commission is always collected in source currency. For example, if you want to exchange 100 US Dollars into Russian Rubles at the exchange point, where the exchange rate is 29.75, and the commission is 0.39 you will get (100 - 0.39) * 29.75 = 2963.3975RUR. You surely know that there are N different currencies you can deal with in our city. Let us assign unique integer number from 1 to N to each currency. Then each exchange point can be described with 6 numbers: integer A and B - numbers of currencies it exchanges, and real RAB, CAB, RBA and CBA - exchange rates and commissions when exchanging A to B and B to A respectively. Nick has some money in currency S and wonders if he can somehow, after some exchange operations, increase his capital. Of course, he wants to have his money in currency S in the end. Help him to answer this difficult question. Nick must always have non-negative sum of money while making his operations. Input The first line contains four numbers: N - the number of currencies, M - the number of exchange points, S - the number of currency Nick has and V - the quantity of currency units he has. The following M lines contain 6 numbers each - the description of the corresponding exchange point - in specified above order. Numbers are separated by one or more spaces. 1 ≤ S ≤ N ≤ 100, 1 ≤ M ≤ 100, V is real number, 0 ≤ V ≤ 103. For each point exchange rates and commissions are real, given with at most two digits after the decimal point, 10-2 ≤ rate ≤ 102, 0 ≤ commission ≤ 102. Let us call some sequence of the exchange operations simple if no exchange point is used more than once in this sequence. You may assume that ratio of the numeric values of the sums at the end and at the beginning of any simple sequence of the exchange operations will be less than 104. Output If Nick can increase his wealth, output YES, in other case output NO.
