In simple terms, variable store values and pointers store the address of the variable. Pointer Declaration: Like variables, pointers should be declared before using it in the program. We can name pointers anything as long as they obey C’s naming rules. Syntax:Data_type * pointer_variable_nam...
The answer is fairly simple; a smart pointer is a pointer which is smart. What does that mean? Actually, smart pointers are objects which behave like pointers but do more than a pointer. These objects are flexible as pointers and have the advantage of being an object (like constructor and ...
/* A simple program that prints all its arguments. It doesn't use argc ("argument count"); instead, it takes advantage of the fact that the last value in argv ("argument vector") is a null pointer. */ #include #include int main( int argc, char **argv) { int i; printf...
We have already discussed it in C programming pointers, here I am writing a simple example in C++ programming language to declare, initialize and access the pointers.Pointer in C++Pointers are the variables (a type of special), which stores the address of another variables.Pointers can store ...
Great article, it contained great detail and simple explanations of pointers. Thanks. ∞ samadhanJuly 5, 2012, 7:57 am u have explain the concept in nicely in manner, easy to understand ∞ zahJuly 24, 2012, 4:12 am Thanks for this article mayn!! really useful! I think I got what ...
Because this function returns TRUE or FALSE, it can be passed to one of the_ASSERTmacros to create a simple debugging error handling mechanism. The following example will cause an assertion failure if the memory range is not valid for both reading and writing operations: ...
As you would expect, this program produces the result: 2 Somehow, when we call simple.setID(2);, C++ knows that function setID() should operate on object simple, and that m_id actually refers to simple.m_id. The answer is that C++ utilizes a hidden pointer named this! In this les...

As you can see, it is a very simple program, but the output I get is: ifx -o chkstring chkstring.f90 #0 0x000000000232d5da #1 0x0000000002394df7 #2 0x0000000002394dc6 #3 0x000000000237f88c #4 0x0000000002437730 #5 0x000000000243726b #6 0x00000000023d2f57 #7 0x00000000023d26bc #8 ...
