Exercise 4 (Assessed exercise) Write a computer program that takes three numbers of the user and finds: * The maximum of the three e The minimum of the three e The average of the three * The difference between the maximum number and the minimum number The difference between the maximum number and the m<.m_ number the absolute value of minimum number. note: you should not use predefined function abs. must implement your own function. o a positive is itself absolution negative v for example which equal to make sure that program designed in modular way. always follow good practice described previous exercise i.e. at least one .h file call it mymath.h will contain definitions functions and two .c files: main.c only main another mymath.c implementation functions. this way end up with three files. compile everything command: . gcc command then output single executable called main.exe. case contains errors list errors. g_.mmm messages pay attention error occurred line within occurred. fix first first.>
