Value Returning Function Exercise: avg()

In this exercise you will practice writing and using value returning functions by writing a C++ program that asks the user to enter five integer marks, uses a function to calculates the average of the five marks, then prints the average.

• Add code to template file ex3_average.cpp in the replit team project or create it in your IDE.
• Declare 5 integers in main().
• Prompt for and read five integer marks in main().
• Write and use a value returning function with five integer parameters to calculate and return the average to the calling function, main().
  Here is a partial prototype for you to use:

  avg(int, int, int, int, int);

  Be sure the calculation in the function produces decimal places for a more precise average. You must determine a return type that will preserve those decimal places.
• Print the average in the main() function.
• Compile and run the C++ program.
• Test the program with an input guaranteed to produce decimal places. For example:

  
  Please enter 5 integer marks: 1 2 1 1 1
  The average of those marks is: 1.2
  

When you are done:

• Take a screenshot of your IDE and console window after compiling and running the program.
• For this exercise, you will have: ex3_average.cpp.
• If you have completed everything, congratulations! Please download a zip file from replit and upload it to URCourses.
