Another point that might be confusing. When you first introduced the concept of a pointer, you used the following example:
// declare an int variable and an int pointer variable
int number;
int* pointer;
My thinking was that a pointer had to be an integer since it was an address in memory, so that made sense. Then in a subsequent example you declared...
This confused me, since how could an address, i.e. pointer, be a float? Later did I realize that the way to interpret "float* " or "int*" is, respectively, "a float's pointer" or "an integer's pointer". Another way to think of it is "a pointer for a integer variable" or "a pointer for a float variable".
