C++ Reading a .txt file
In C++, I am attempting to read several fields for a text file into my program. I was told I could use the code below to fetch the c-sting variable housed in the middle of the .txt file. I am having no luck getting the cin.get() to work in the middle of the code.
suggested code:
char name[21];
cin.get( name, 21, '\n' );
========================== ==========
The code that I am using is my .txt file is name "masterFile".:
masterFile >> ID >> name >>payRate >> dependents >> eType;
A sample of the text file is below:
5 Christine Kim 30.00 2 1
15 Ray Allrich 10.25 0 0
16 Adrian Bailey 12.50 0 0
17 Juan Gonzales 30.00 1 1
18 Morris Kramer 8.95 0 0
22 Cindy Burke 15.00 1 0
24 Esther Bianco 10.25 0 0
25 Jim Moore 27.50 3 1
32 Paula Cameron 14.50 0 0
36 Melvin Ducan 10.25 0 0
37 Nina Kamran 30.00 1 1
38 Julie Brown 35.00 0 1
40 Imelda Buentello 14.50 0 0
42 J. P. Morgan 12.50 0 0
43 Maria Diaz 15.00 0 0

good work. great job!!!
Fortunately, you data is fixed width, so you can use:
char line[100];
while(!masterFile.getline(
{
}
then you can extract string portions at specific positions to obtain the fields.
