我收到此错误:
严重级代码描述项目文件行抑制状态 错误C2910'addingStuff :: addingStuffFunc': 不能明确 专门的BuckysTemplateSpecialization c:\ users \ amanuel \ documents \ visual 工作室 2015 \项目\ buckystemplatespecialization \ buckystemplatespecializ
当我尝试运行此代码时:
#include<iostream>
#include<string>
template<class F, class S>
class addingStuff {
public:
addingStuff(F fCons, S sCons) : f(fCons), s(sCons){}
F addingStuffFunc();
private:
F f; S s;
};
template<class F, class S>
F addingStuff<F, S>::addingStuffFunc() {
return(f + s);
}
template<>
class addingStuff<std::string , std::string>{
public:
addingStuff(std::string sConst, std::string s2Const):s(sConst), s2(s2Const){}
std::string addingStuffFunc();
private:
std::string s, s2;
};
template<>
std::string addingStuff<std::string, std::string>::addingStuffFunc() {
return "Sorry.. Adding strings is Illegal!!";
}
int main() {
addingStuff<std::string, std::string> exampleStuff("Hello " , "World");
std::cout << exampleStuff.addingStuffFunc() << std::endl;
}
没有线索为什么......
答案 0 :(得分:8)
你只想:
std::string addingStuff<std::string, std::string>::addingStuffFunc() {
return "Sorry.. Adding strings is Illegal!!";
}
额外的template <>
被解释为成员函数的模板ID,代码被解释为<>
的明确特征。但是addingStuffFunc
不是函数模板,因此是错误。
