Pointer instructions create a new folder setxc and a new project lxc with main. cpp that does the following: 1. declare an integer named inum with initial value 9
2. declare a double named dnum with initial value 14.25
3. declare two pointers to integers named iptr1 and iptr2
4. declare a pointer to a double named dptr.
5. assign the address of inum to iptr1
6. output the address of inum and be sure to identify to the user what you are displaying. there are two ways you can do this; you should do both, to convince yourself they are the same.
7. use iptr1 to display the contents of inum
8. try to assign the address of dnum to iptr1. what error message do you see? comment out this bad line of code, but include the error message as a comment directly below.
9. assign the address of dnum to dptr.
10. output the address and then the contents of dnum (using dptr)
11. directly change the value of inum to 7.
12. use iptr1 to output the contents of inum
13. assign iptr2 to have the same value as iptr1. do not reference inum; instead use the address stored in iptr1
14. output the address in iptr2. this should be the same as displayed in step 6
15. output the value pointed to by iptr2
16. using iptr2, change the contents of inum to 12.
17. output the contents of inum three times, first using iptr1, then using iptr2, then inum directly. in each case, identify what the user is seeing appropriately.
