std::cout << std::endl; return 0; } 在这个例子中,我们使用using MyVector = std::vector<T>语句定义了一个名为MyVector的模板类型别名,从而可以使用MyVector<int>来代替std::vector<int>类型。 4、using function using function可以将一个函数定义为另一个函数的别名。例如:
std::cout<< __PRETTY_FUNCTION__ << val1 + val2 <<std::endl; }voidMyFunc2(intval1,intval2) { std::cout<< __PRETTY_FUNCTION__ << val1 + val2 <<std::endl; }voidFunctionBindTest(void) { std::function<void(int)> pb = std::bind(MyFunc1,10, std::placeholders::_1); pb(1...
这时,我们可以使用using来创建一个别名,如using StringVecIt = std::vector<std::string>::iterator。这样,在后续的代码中,我们只需要使用StringVecIt就可以代表那个冗长的类型,这使得代码更加清晰明了,如同给复杂的道路命名,让人们更容易找到方向。此外,using还可以用于类的继承中的基类成员引入。在类的继承...

解析 1)你的主函数声明了返回整型,但你没有用return返回值。如果你没有什么可返回的值,那你就把函数返回类型声明为void。 2)end1改为endl。 #include usingnamespacestd; #defineA10 //intmain()改为voidmain() voidmain() { inta[A]; cout反馈 收藏 ...

Note that you create a window using the new_ function and delete it using the delete_ function (again, it's usually the user who closes a window). Additionally, if you have a window of type X (window_base is the default), and you want to know if it's of type...
Various approaches58,59,60have also been applied to sorting functions that run in the single instruction, multiple data (SIMD)61setup. This setup is capable of parallelizing instruction execution, but is not supported at present in popular libraries such as LLVM’s libc++ std::sort library. On...
