Question

Please I need help in C language, I am trying to modify the code per the below instructions, but I am getting errors. Can't fgure it out. The attempted code modification and data file is privided below, after the instructions. Thank you.

Instructions:                 

1.      First, add a function named printMsg that displays a message, a greeting, or an introduction to the program for the user. Add a statement that calls that function from the main function when your program starts. This function does not return anything, and you may define your own message. Define this function below main, and add a function prototype statement at top of your program to avoid creating an error flagged by the compiler.

2.      Next, examine your Lab 3 code to identify a computational task that could be successfully removed from main and placed in a separate function instead. Examples of discrete tasks might include:

·       Identifying the minimum value in an array

·       Identifying the maximum value in an array

·       Computing the sum and/or average of values in an array

Define the function to complete the task, placing it below main. You will need to provide a name for this function that matches the task that it performs. Add a function prototype statement for this function at the top of your program.   Add the statement to main that will call this function and handle what is returned. Comment out the lines no longer needed in main.

3.      Test your program using the same data file as used for Lab 3. Your program should produce the identical results as obtained with your program from Lab 3 (with the addition of the greeting/introduction). Capture a screenshot and place it in a Lab Report.
