C++ pointer help

all right then, i'll try to practice it. but one more question..... mjordan2nd's link says that the pointer point to an address in the memory, right? but you say that it has to do w/ the variable's value, right? so which one is right? they can't both be correct, right? so which one is it? and sorry for being a pain in the rear w/ all this confusion i have. i just don't catch things so easily sometimes thanks for your help guys.

They are both correct. A pointer holds an address in memory. If you outputted the value of a pointer, you would get a memory address, which pretty much would look like random garble. However, you can use a pointer to change the value of a variable as well. By using the correct command, you basically say change the value of the address a pointer is pointing to. For instance, lets say pointer i points to variable x, and variable x's location in memory is 1234:5678. Lets say x is initially 10. If you wanted to change x's value to 20, you could do so using the pointer like so:

*i = 20;

What that code does is it says, go to the address that i is holding, which also happens to be variable x's location, and change the value that address i is holding to 20, which therefore also changes x's value.
