I need help with programs

This is what I am suppose to complete:

For each of the following, write a single statement that performs the specified tasks. Assume the long integer variables value1 to value2 have been declared and that value1 has been initialized to 200000.

a) Declare the variable longPtr to be a pointer to an object of type long.

b) Assign the address of variable value1 to pointer variable longPtr

c) Print the value of object pointed to by longPtr

d) Assing the value of the object pointed to by longPtr to variable value2

e) Print the value of value2

f) Print the address of value1

g) Print the address stored in longPtr.

Below is what I came up with. I would appreciate any help tha you can offer.


a.) int longPtr *value1[200000];

b.) longPtr=&value1;

c.) printf(longPtr=value1);

d.) int longPtr *value2[1];

e.) int printf = value2;

f.) int printf(address of value1);

g. ) int printf; (longPtr = address);

Homework?

Post a specific questions.

new? :)

Code:

---

1) long *longPtr; //declares a pointer to a long
2) longPtr = &variable1; //assigns the address of (&) variable1 to longPtr
3) std::cout << *longPtr; //prints the value pointed to by (*) longPtr
4) variable2 = *longPtr; //assigns the value pointed to by (*) longPtr to variable2
5) std::cout << variable2; //prints the value of variable2
6) std::cout << &variable1; //prints the address of (&) variable1
7) std::cout << longPtr; //prints the value of longPtr, which is the address of variable1 right now

It's written in C++ (i.e. the std::cout's, but those are the c++ version of printf()), you might learn something ;)
P.S. this looks like C, but it's posted in the C++ forum.

I really appreciate your help.

Any day :) After all, you did try for yourself.
