The above code defines a functionprintIntthat takes a void pointer num as a parameter and casts it to an integer pointer using thestatic_cast operator. The function then prints the value of the integer pointed to by the casted pointer. In the main function, an integer variable x is defined...

Method 2: Find a Variable’s Memory Address Using a Pointer In C++, variable addresses can also be obtained using pointers. A variable that holds another variable’s address is referred to as a pointer. A pointer serves like any other variable that must be specified before it can be utilize...
class node { private: int data; node* next; //pointer to object of same type public: //Member functions. }; ExplanationIn this declaration, the statement node *next; represents the self-reverential class declaration, node is the name of same class and next the pointer to class (object ...
In the example above, a constructor is defined to accept an error message and a private member variable is used to store the error message. You can now throw instances of your exception class within your code using the throw keyword.Example To catch and handle the thrown exception, you can...
• Pointer expressions:The expressions that give address values as output are calledpointerexpressions.For example, &x, ptr and -ptr are pointer expressions. Here, x is a variable of any type and ptr is a pointer. • Special assignment expressions:An expression can be categorized further dep...

In the following code, incrementing the variable sum has undefined behavior as the increment in the first iteration of the loop means it will be read from before it has been initialized: /* *a : Pointer to an array of signed integers n : Number of elements in the array */ int func(...
[sourcecode language=”cpp”] int * a = get_integer(); int & b = *a; [/sourcecode] “b” now refers to the object pointed to by “a”. There is no way at this point at the code to know what “name”, if any , “b” is bound to. It is no longer related to “a” ...
