Question

I am trying to modify this program so that it stores the employee's name in a c-string and can handle up to 100 employees (so it would mostly be a partially filled array), but I cannot get it to work. It works with two files that it is suppose to read input from. Then it prints output to an output file.

Employee Info File (first file read, M/F should be ignored):

5    Christine Kim 30.00   2       1    F

15    Ray Allrich                 10.25     0      0    M

16    Adrian Bailey 12.50     0      0    F

17    Juan Gonzales 30.00    1     1    M

18    Morris Kramer 8.95     0     0    M

22    Cindy Burke               15.00    1    0     F

24    Esther Bianco            10.25    0    0     F

25    Jim Moore 27.50    3     1     M

32    Paula Cameron         14.50    0    0     F

36    Melvin Ducan            10.25    0   0     M

37    Nina Kamran             30.00    1   1    F

38    Julie Brown                35.00    0   1     F

40    Imelda Buentello 14.50    0   0     F

42    J. P. Morgan              12.50    0    0     M

43    Maria Diaz                 15.00    0   0     F

Timecard File with ID number and hours worked (second file read):
