Except a few, most of the programs in C may be written with or without pointers. Then the question arises “Why use pointers if you can do without them?” Pointers are considered to be useful tools in programming because of the following reasons: (i) Pointers make the programs simple and...
It may be noted that as a C programmer, we do not need to know the actual address stored in a pointer variable in most situations. Moreover, the pointer variable may physically be present anywhere in main memory, either before the variable it points to or after it. Hence, an arrow is ...
Note: In this article, “Python” will refer to the reference implementation of Python in C, otherwise known as CPython. As the article discusses some internals of the language, these notes are true for CPython 3.7 but may not be true in future or past iterations of the language....
They finally fixed it in VC7. Intel uses the same calculation as MSVC, but their /vmg option behaves quite differently (it has almost no effect - it only affects the unknown_inheritance case). The release notes for their compiler state that conversions between pointer to member types are ...
Final notes Iterators behave like pointers: can't I just use them? Our custom container is a wrapper around an old-school array, which can be navigated with pointer arithmetic. Indeed we could get rid of the whole Iterator class and just return a pointer to the first and last array elemen...
The sample includes the required parts of boost, so no additional downloads are necessary - but please read the boost installations notes, below. The following sample uses a scoped_ptr for automatic destruction: Using normal pointers Using scoped_ptr void Sample1_Plain() { CSample * pSample(...

Pointer variables may be passed as parameters in function and procedure arguments. Pointer variables can be passed on both as value and variable parameters; however, when passed as variable parameters, the subprogram might inadvertently alter the value of the pointer which will lead to strange ...
Just like every variable in a program has an address, every function in a program too has an address. The name of the function can be used to obtain the address of a function. This address can be stored in a special type of variable which are pointers to
