Pointer to an array of integers in C programming language, learn: How to declare a pointer of a array, how to initialize it with the array address and how to access the elements of the array using pointer?
I want to do something like above where I can create an array of temp_struct derived data types pointing to the existing array. I tried to do it various ways but the only solution that worked for me was by copying the data, which I don't want to do. ...
受保护的指针(A guarded pointer)QPointer<T>的行为类似于普通的 C++ 指针T*,但不同的是当所引用的对象被销毁时(普通的 C++ 指针则会变成“悬空指针”),QPointer会自动清除。T必须是QObject的子类。 当需要存储指向由其他人拥有的QObject的指针时,受保护的指针非常有用,因为在您仍然持有对它的引用时,该对象...
