Write a program in C++ language to illustrates how a pointer variable works. Follow the instruction below; - Create main function and include your information details - Declare the pointer variable of p as an integer - Declare an integer variable of num1 and num2, and set the value of num1 = 5 and    num2 = 8 - Store the address of num1 into p - Print the address of &num1 and value of p - Print the value of num1 and *p - Change the value of *p to 10 - Print the value of num1 and *p - Store the address of num2 into p - Print the address of &num2 and value of p - Print the value of num2 and *p - Multiply the value of *p by 2 - Print the value of num2 and *p
