How does the unique_ptr Function Work in C++? The C++ programming has n number of reserved keywords, functions, and pointers that will provide some level of abstractions from the actual namespaces as well as the new libraries which are being already used for the programmers to allow it with ...
access fields in a struct or elements of an array: equivalent to f := unsafe.Pointer(&s.f) f := unsafe.Pointer(uintptr(unsafe.Pointer(&s)) + unsafe.Offsetof(s.f)) equivalent to e := unsafe.Pointer(&x[i]) e := unsafe.Pointer(uintptr(unsafe.Pointer(&x[0])) + i*unsafe.Size...

Hello everyone, i'm porting an application from C# to C++, and i find the syntax and all that of C++ rather cumbersome (though C/C++ was my first language). I have a very specific question, and another one unrelated The specific question: In C#:...
auto_ptr<x> m_SMPTRx(new x(m_PARAMin)); m_SMPTRx->DoSomething(); } OK!你不太相信.不用delete吗? 是的.不用整天提心吊胆的问自己:"我全部delete了吗?",而且比你的delete 策略更安全. 然后,还有人告诉你,可以这样用呢: ok1. auto_ptr<x> m_SMPTR1(new x(m_PARAMin)); ...
