I am having trouble understanding this code. All I really need is to modify the head pointer to point to the first element. So why won\'t *head work ? Changing the value of *head changes where this po
I am writing a wrapper around C DLL in C++/CLI so that it can be accessed in C# through a managed assembly. Using direct P/Invoke to access C functions via C# is not possible because C DLL raises exce
Is it appropriate way to keeps the pointers in statically allocated array this way in C++? void *data[1000];
#include <stdio.h> #include <stdlib.h> const int * func() { int * i = malloc(sizeof(int)); (*i) = 5;// initialize the value of the memory area
Note: I am using the g++ compiler (which is I hear is pretty good and supposed to be pretty close to the standard).
I\'m writing a linux kernel module that makes use of the exported symbol open_exec struct file *open_exec(const char *name)
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references,or expertise, but this question will likely solicit debate, a
Please, don\'t misunderstand the question. I know that implementation of the pointers in these two languages is identical, as C is a subset of Objective C.
According to ISO C++, dereferencing a null pointer is undefined behaviour. My curiosity is, why? Why standard has decided to declare it undefined behaviour? What is the rationale behind this decision?
The problem this: at the end of this function, the members of the element at \"tasks[taskCount]\" like name, due date, etc, are indeed what was passed into this function, but after returning to this f
