Pointer in C++: A pointer is a variable whose value will be another variable’s address. Generally, a pointer variable is declared as follows: type var-name; Here, type is the pointer’s base type and var-name is the pointer variable name. The asterisk is used to designate a variable as a pointer. Given Program: //Include libraries #include <iostream> //Use namespace using namespace std; //Define main method int main() { // Declare pointer variables int p1, p2; //Assign value p1 = new int; //Assign value p2 = new int; //Assign value p1 = 10; //Assign value p2 = 20; //Display value cout << p1 << " " << p2 << endl; //Assign value p1 = p2; //Display value cout << p1 << " " << p2 << endl; //Assign value p1 = 30; //Display value cout << p1 << " " << p2 << endl; //Pause console window system("pause"); //Return 0 value return 0; }
