I am writing some simple shader compilation code and during one point I use a vector of chars to store an error log if things go wrong. The problem is of course that the compiler refuses to accept that vector is in std:: (this is a probl...

在C++17之前,模版类的构造函数在调用时必须指明类型,不能进行隐式类型推导;但是调用普通模版函数时是可以不显式指明类型的,这是因为普通模板函数可以进行隐式类型推导,下面代码以pair、tuple和vector为例展示了这一现象: 在C++17之后,模板类的构造函数也可以进行隐式类型推导: ...
