**use ONLY “stdio.h” library**

Write two functions in a single program. After writing following functions, call them from** main **function to test if they are working correctly (how functions will be tested depends on programmer).

i) Write a function that will receive two integer variables (x,y) as parameter. This function will find and show on screen all odd numbers between x and y (both included and order of x and y, while sending them to defined function, is not important).

ii) Write a function that will perform following mathematical expression (note that, x, y and z are integer values), and return result.
