Problem $2$

This problem is designed to make sure you can write a program that reads data into an array of

structures from a file and prints out the contents of the array you have populated. This will be

especially important, since to test data structures we will need a lot of data and it will be far

more than you can type in$!$

The file to be processed is provided with the exercise. It is named "Problem$1\_2$DataFile.txt$".$ If

you open it$,$ you will see it contains multiple lines. Each contains a name, an age, and a salary.

The Solution $/$ Test Requirements

I want your program to demonstrate that you can define a struct that has $3$ fields. They are

Name, Age and Salary. The struct is to be declared using a typedef. The Name field is a

character array sized to hold $30$ characters and a NULL $($zero byte$)$ at the end. Both the Age

and Salary fields are integers.

Two functions are needed to augment your test main.

GetData is a function that is called by your test main to populate the array. It is passed the file

name to open $/$ read $/$ close, the array to populate and the maximum number of array entries to

fill from the file. It will need to open the file, read in as many items as the test main has

requested and close the file. It must return the number of array items that have been filled.

ShowData is a function called to display the array contents on the console. It will need to

receive the array and the number of items to print. It should print the number of items being

requested to be printed and then iterate through the array, printing out the Name, Age and

Salary fields for the requested number of items. You should use a $\%$s format to print out the

Name field.

Your Test Main must:

Create the array of the structure type. The size of the array is to be fixed at $10.$

Get the number of items to actually place in the array by prompting the user for a

number from $1$ to $10.$ If you get a number outside the range, you must exit your

program. Otherwise,

a$.$ You must call GetData, passing it the file name to use, the array to fill and the

number of items to place in the array. Remember that GetData will return the

number of items actually placed in the array.

b$.$ On return from GetData, you must call ShowData, passing it the array and the

number of items returned by GetData.

Run your program, for $3,6$ and $10$ items, submitting all runs with your code.
