Another Pointer

Just to add a little intrigue to the system, we have another pointer defined in this program, "pt2". Since "pt2" has not been assigned a value prior to statement seven, it doesn’t point to anything, it contains garbage. Of course, that is also true of any variable until a value is assigned to it. Statement seven assigns "pt2" the same address as "pt1", so that now "pt2" also points to the variable "index". So to continue the definition from the last paragraph, anyplace in the program where it is permissible to use the variable "index", it is also permissible to use the name "*pt2" because they are identical in meaning. This fact is illustrated in the first "printf" statement since this statement uses the three means of identifying the same variable to print out the same variable three times
