in a very scientific way, In a series of short, tightly-targeted lessons, you will learn all about: Computer memory and how pointers access it How memory is allocated What happens when you ‘cast’ pointers to

In this tutorial, you will learn about thedangling pointer,void pointer,NULL, andwild pointerin C. I have already written a brief article on these topics. The main aim of this blog post to give you a quick introduction to these important concepts. Also, I will describe different states of...
So, the question here is whether void* is a pointer to an "object type", or equivalently, whether void is an "object type". The definition for "object type" is: 6.2.5.1: Types are partitioned into object types (types that fully describe objects) , function types (types that describe ...
typedef returnTypetypeName(parameterTypes); (example code) How Do I Do It in C++? (C++11 and later) As afunction pointer type alias: usingtypeName=returnType(*)(parameterTypes); (example code) As afunction type alias: usingtypeName=returnType(parameterTypes); ...
However, the result may be undefined because of the alignment requirements and sizes of different types in storage. A pointer to an object can be converted to a pointer to an object whose type requires less or equally strict storage alignment, and back again without change. A pointer to void...
http://stackoverflow.com/questions/3523145/pointer-arithmetic-for-void-pointer-in-c When a pointer to a particular type (say int, char, float, ..) is incremented, its value is increased by the size of that data type. If a void pointer which points to data of size x is incremented, ...

You can declare variables of the other iSeries 400 pointer types by using the type definitions (typedefs) that are provided by the ILE C <pointer.h> header file. Figure 188 shows iSeries C pointer declarations. Figure 189 shows iSeries C++ pointer declarations. ...
typedef returnType typeName(parameterTypes); (example code) How Do I Do It in C++? (C++11 and later)C++ offers several compelling alternatives to C-style function pointers such as templates and std::function with std::bind. If you really want to use function pointers in C++, you can stil...
