Question

C++ programming

Pointers

Create a program that creates and initializes: a character, an int, a short, a long, a double, a float

Create pointers to each.

creates and initializes 6 integer values.

creates and initializes an integer pointer

prints out: the value of the integer value, the value of its address, the value of the pointer and the value the pointer points at.

Change the integer value using the pointer.

print it all out again.

repeat for the other five integers.

Your result should look something like the picture...but little bit different..
