C Programming - Exercises Session 02

Pointers, Arrays and Memory Management

1. Implement a program with a main function and two other functions:

   • power(int x, int y) – should return “x to the power of y”, for instance power(2,3)=8
   • multiSwap – should take three integer-parameters x, y and z. After a call to multiSwap, x should be equal to the old y, y should be equal to the old z and z should be equal to the old x. The return type of multiSwap should be void.

2. Write a function named sum_arrays that takes two arrays as parameters, totals the values in both arrays and returns the total. Test your function by making a program that calls it.

3. Write a function that takes two integer arrays as parameters, combines and sorts the values into a new array and returns that array. Make a program that calls your function and verifies the result.
