1. explicitinstantiation of template function In a.h, an interface of template function is declared, and the implementation of the template function is defined in a.cc. In a.cc, we should add code to specify certain type of instatiations of the function so that the instantiation can be co...
cpp: In function 'void test(A<T>&)': template_test.cpp:11:10: error: expected primary-expression before 'int' a.hello<int>(); ^ template_test.cpp:11:10: error: expected ';' before 'int' 解决这个问题的办法很简单修改A::hello函数的调用方式,增加template关键字申明hello为模板函数 代码...
template<classT>or template<typenameT> template<> 对函数声明或定义进行修饰,其中 T 可以是任意名字(例如Object)。 进行在模板函数调用时,编译器会根据变量类型推断函数参数类型。 那么,函数模板是否可以支持多种类型呢?可以! 代码语言:javascript 代码运行次数:0 ...
一.引子在成员模板使用过程中,出现了意想不到的bug。如下: class A { public: template<class T> T function_m() { } }; template<class U> void function_n(U argument) { char object_x = argumen…
