 Some global constants.  With this set up, to make the program work

 there.

 The purpose of function getData is to
 + read from the input file whose name is stored in: fname,
 + read the first number in the file to determine how many
 data items are in the rest of the file,
 + copy the data items in the file into the array called: data, and
 + set the parameter numSlotsUsed equal to the number of
 items copied into the array.
 
 (Function getData copies the first data item in the file, if one
 exists, into data[0], copies the second data item into data[1], and so
 on.)
 
 Function getData handles the following exceptional situations:
 + input file cannot be opened,
 + input file has no data items, and
 + input file contains more data items than the value of arraySize.
 
 In those situations, function getData prints an error message and
 terminates execution of the program (It calls the exit() function.).

Hi @unik,

This is a
simple example.

Eyenrique-MacBook-Pro:Desktop Eyenrique$ ./getData 
Enter name: Alex Ferguson                
Enter his/her number: 10
Enter name: David Moyes
Enter his/her number: -1
Enter name: Jose Mourinho
Enter his/her number: 10

Name              Number
Alex Ferguson        10
David Moyes          -1
Jose Mourinho        10
