Write a function float max(float n1, float n2); that returns the greater of n1 and n2. Write a function float min(float n1, float n2); that returns the lesser of n1 and n2. Write a program that reads in numbers and uses the above functions to find the maximum and the minimum of all the numbers. The end of input occurs when zero is typed. Zero is a valid number for determining the maximum and the minimum. Use debug statements to ensure that the maximum and the minimum are updated correctly.

 

For the first part, write the functions max() and min() in the file maxmin.c. Put the prototypes for these functions in the file maxmin.h (and don't forget to include this header where needed). Then write a test driver, main(), to test these functions in the file driver1.c. The driver should allow the user to test these functions by entering one pair of float values and verify the functions return the correct values each time. Use end-of-file to end the test input. You can then compile this program with the command:

cc driver1.c maxmin.c
