ifstream from text file
I'm having trouble pulling text and numbers from a text file.
I need to read one line at a time.
my text file looks like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14

exit(1);

else

while (!inFile.eof())

What exactly are you trying to do, and what isn't working?
to place everything in the text file into "row 0" of the array.
could i grab one character at a time in a for loop until a new line or space?
hope this will help
insted cout, simply pass the data to an array

string data;
ifstream inFile("name.txt");
while(inFile >> data){
cout << data << endl;

i need to pull in one line at a time though, because the text file consist of data that needs to go to different places.
Your program mostly works, if you take out the "for section" data is read and output. The for section restricts the output.
Maybe you are asking the wrong question. Maybe by telling us what you intend to do with it, after you read it would help.

i need to store the text file in 4 different arrays.
the name should go in the first array, then the 5 quizzes in the second array, then
4 assignments in the third, then 2 tests in the last array.

variables in caps are global variables in a header file.
Thanks for the help
