Task 1Write a C++ program that declares int variables x and y and int* pointer variables p and q. Set x to 2, y to 8, p to the address of x, and q to the address of y. Then print the following information: (1) The address of x and the value of x. (2) The value of p and the value of *p. (3) The address of y and the value of y. (4) The value of q and the value of *q. (5) The address of p (not its contents!). (6) The address of q (not its contents!). Procedure/Program: #include<iostream> #include<conio.h> using namespace std; int main() { int x, y; int *p; int*q; x = 2; y = 8; p = &x; q = &y; cout << &x<<endl; cout << x<<endl; cout << p << endl; cout << *p<<endl; cout << &y<<endl; cout << y<<endl; cout << q<<endl; cout << *q<<endl;
