program C HELP.
- In the program I need to make a input three real (floating point) numbers from the keyboard and calculate a number of properties about the numbers.
-3 values would read a single scanf() statement.
-Then call each of five functions you will write.
-Each function will pass the three values that are input the function will perform the requested calculation. then return the required result.
- functions to be written are----
- Determine which of 3 #'s is largest and return that value.
-Determine which of 3#'s values is the smallest and return that value.
-Determine if all 3 #'s are equal to each other.
Return the character ‘=’ if they are, or the character ‘#’ if two or more have different values.
Calculate and return the average of the 3 values
An example is attached when run.
This program will calculate several properties with respect to three floating point values entered. Enter three real numbers 6.05 6.1 7.5 val 1 val 2 val 3 Max Min Avg All-Equal Near-Equal Epsilon I I 6.05 6.10 7.50 7.50 6.05 6.55 No YesExplanation / Answer
