Write a program to open an input file and output file. The user is prompted for both filenames and the
program must verify that both files opened. The file contains first and last names separated by a space.
Some individuals listed are only known by their first name, in these cases, “noLastName” has been put
as a place holder in the file to make processing easier. Replace “noLastName” with “ “ in the output.
The program should open using the filename provided by the user for input and the supplied output
filename for writing. The user is prompted as to whether the entire file should be read. If yes, then all
records in the file should be processed until end of file is reached. If no, then only the specified records
are processed.
The program reads the first and last name fields from the input file. The header should be written to
the output file first, see examples for formatting. As each name is read from the input file, the current
record number along with the name are written out to the output file. Each name is assigned a droid
type and model. If the first name indicates the person is in a management position, they are
automatically assigned an administrative droid type. The model of the droid is decided by selecting a
random number, which is mapped to the types and models using the following enumerated types.
enum DROID_TYPES { ADMINISTRATIVE, MAINTENANCE, PROTOCOL, ASTROMECH };
enum ADMINISTRATIVE_TYPES { ET_74, XA_540, a3D_4X};
enum MAINTENANCE_TYPES { F1_DX, EB_89, CB_2B, SA_45};
enum PROTOCOL_TYPES {C3PO, L80, SA_5, RA_7 };
enum ASTROMECH_TYPES { M4_Y6, BB_8, D3_S5, R2_D2};

Individuals that do not have titles showing they are in management, have a droid type and model
selected for them randomly.
The type and model assigned are written to the output file after the first and last names. The number of
each type of droid assigned should be kept in a counter and total output at the end of the file.
File Data Format:
The file format is as follows:
Admiral Sarn
Saul Karath
Assignment Notes
The random number generator returns an integer, which needs to be converted to the type specified.
Because enumerated data types are base on the integer data type, a simple static cast can be used to
convert the integer from the random number to the desired enumerated data type.
Example
DROID_TYPES droid=ADMINISTRATIVE;
int value =0;
value = rand( ) % 5; // random number limited in range from 0-4.
// assign the integer to droid
droid = static_cast<DROID_TYPE> (value);
// now droid maybe used in a switch statement with case labels of the enumerated type
//DROID_TYPES.
Random Number Generator Notes
Do not initialize the random number generator seed with srand().
File Input Notes:
If the user selected to read the entire file, then all data in the file should be processed. If the user
selected to enter a number of lines to process, then the only the entered number of lines should be read
and included in the statistics. Be aware that the user may enter a number that is larger than the number
of lines of data in the file. When the program stops reading the file, a message should be displayed
stating why the reading stopped, end of file or maximum number of records requested. See example
for formatting information.
Input File:
The data file is on the canvas website.
Compiling
Purpose:
Become familiar with basic C++ syntax, input/output, if statements, C++ looping structures, file I/O,
output formatting and recovering from bad input that causes the input stream to go to the fail state.
Rebel Alliance Computational Support has been asked to write a program to assign droids to personnel.
The droids are randomly assigned to each person, unless the person is a manager, then they are always
assigned an administrative droid. Managers have a title in place of their first name and include
Admiral, Captain, Commander, Darth, Emperor, and Queen. All other individuals have the droid type
and model assigned using the random number generator.
