A pointer variable can be created not only for built-in types like (int, float, double etc.) but they can also be created for user defined types like structure. If you do not know what pointers are, visit C++ pointers. Example: Pointers to Structure #include <iostream> using namespace ...
Sometimes a question arose"Can a structure has private members?" The answer is"Yes! In C++, we can declare private members in the structure". So the important thing is that"we can declare a structure just like a class with private and public members". ...

A member can't be declared to have the type of the structure in which it appears. However, a member can be declared as a pointer to the structure type in which it appears as long as the structure type has a tag. It allows you to create linked lists of structures. ...
pointer that can hold a single value. Non-Primitive Data structure The non-primitive data structure is divided into two types: Linear data structureNon-linear data structure Linear Data Structure The arrangement of data in a sequential manner is known as a linear data structure. The data structu...
CPrintInfo::m_nNumPreviewPagesIdentifies the number of pages displayed in the preview window; either 1 or 2. CPrintInfo::m_nOffsetPageSpecifies offset of a particular DocObject's first page in a combined DocObject print job. CPrintInfo::m_pPDContains a pointer to theCPrintDialogobject used for...
in advance and is defined by another structure field, len. For this example, the code in header1.hpp also defines the create_block function that takes a pointer to Data as an argument and returns the value of len. A simple implementation of crea...

All CUDA threads in a grid execute the same kernel function; It is easy to explain it. When we want to call a kernel function, we will specify the grid and block structure using thedim3data type. It means that we want to use all these threads where locate in the grid to execute thi...
(And it looks like you have control over the type ofhelloso why make it a pointer-to-const since you want to modify what's pointed to? Why isblockedRoadIda parameter instead of a local variable as you never use the value passed into the function?) ...
