C program

Write a C program that calculates and prints the average of two or more salaries entered by the user. The program should first prompt the user to enter the number of salaries to process (make sure: at least 2 salaries must be entered by user! Give an appropriate polite error message of your choice.) . It should then prompt the user for each salary. As each salary is entered, the program should ensure that the salaries entered are in the salary range of zero and above. If the salary is not in that range, an error message should be displayed (as shown below), and the user should be re-prompted for a salary. Any bad salaries entered should not be included

in the average calculation. Once all values are entered, the program should calculate and print the average of all of the positive values entered, rounded off to the nearest whole cent. At the end display a message for the appropriate salary average. This program will feature the if statement as well as programming techniques for data validation. I call it a trap loop. It traps the user into entering valid data.

The dialog with the user could be as follows:

Welcome to the Salary Analyzer.

This program calculates the average of as many

salaries you wish to enter.

First, enter the number of salaries to process: 4

Now enter the 4 salaries to be averaged.

Enter salary #1: 900

Enter salary #2: 800

Enter salary # 3: -200

*** Invalid entry. Salary must be positive. ***

Enter salary #3: 2500

Enter salary #4: 540

The average of the 4 salaries entered is $1185.00

Your salaries are very generous.

Recall: The coral and green text represents the "output" from your program and is shown for clarity only here.

It is not required that your output be in this color. (Do not even attempt to try!). Also note that what the user types in is indicated by the blue area above; Again, for clarity only. A user-friendly message of your choosing should precede the dialog and explain the program as in green above (you should change the first two sentences to personalize it to you). Notice the trap in salary #3. That would repeat continuously until the user enters a correct data value. After the average is displayed, give the final statements based on the following:

If average <= 999.99 display “Your average salaries is low, employees need a raise a raise.”

 If 1000 <= average < = 1999.99 display “Your average salaries are adequate.”

If average = 2000 display “Your average salaries is very generous.”

Also, a trap loop should be used so that at least two salaries are to be entered by the user.

* This program requires variables of type int and float.

* Use printf and scanf statements to first prompt the user for the number of salaries to be processed(don’t forget fflush too).

* This program requires loop structure(s) (for, while or do -- your choice).

* The loop requires some a printf and scanf statement to prompt user for a salary.

* The loop also requires a selection structure (if, or if else) statement to check for bad data values.

* The selection structure requires a printf statement to output error message if improper salary.

* The program requires an accumulator to keep track of the sum of good salaries entered.

* Once all salaries are entered, determine average rounded to the nearest whole cent, and then a printf statement to display the average.
