using c, not c++. Develop a structured C program to 1)enters 3 numbers from the keyboard; 2) call function Max by value to find the maximum of the three numbers and print it on screen; 3)call function Min by value to find the minimum of the three numbers and print it on the screen; 4)calculate the difference between the maximum and minimum; 5)print the difference on screen if the difference >=8; but print on screen The difference between the maximum and the minimum is less than 8! if the difference <8. Max function takes 3 numbers from the main program, compares and returns the maximum. Min function takes 3 numbers from the main program, compares and returns the minimum.
