1. Write a program that declares an int array of 10 elements. Using only pointer notation, populate the array with scanf and print the elements with printf.

2. Write a program where an int pointer p points to a variable x which is initialized to 10. Using only the *, ++ and -- operators with p, (i) add 1 to the address of x, (ii) subtract 1 from x, (iii) add 1 to x.

3. Write a program that uses scanf to accept a word as string input. Using a pointer to a character array and without using array notation, compute the length of the string, i.e. until the NUL character is encountered.

4. Write a program to compute the sum of all elements of an int array using only pointers.
