C/C++ :: Program Runs Into Error After Input Display

The code is supposed to display the total and averages of the data as well, but cuts off due to an error in the code. The code should also:

1)Print checks for all employees, one per page, sorted by lastname. The first check number, 100, is to be read from a company data file (see requirement 4). The border of each check is important and should not be omitted.

2)Convert the net pay to a text string for each check printed.

3)Print a reference code on each check. The reference code is obtained by combining the first letter of the lastname with all the consonants remaining after removing all vowels (a,e,i,o,u).

4)Use the same employee data found in assignment 2. Use company data, obtained from a text file, for each check printed:
