[AdnanAhmed008]

Hey Guys. I need your help. Can someone please tell me the code to write data(Double type e.g 12345.67891) in text file like pattern given below. Remember to put tab between each column.
-----------------------------------------------------
Column1 Column2 Column3
Value 1 Value 2 Value 3
Value 4 Value 5 Value 6
Value 7 Value 8 Value 9
-----------------------------------------------------
& Also how to read data from this file.
Sorry for bad english writing.

Hey AdnanAhmed008

You can use the header file fstream

It is actually pretty neat as I am learning more about it myself.

for example:

ifstream inFile;

inFile.open ("textFile.txt")

inFile >> value1;

cout << value1;

This should get you going. If you are still having an issue, post your code and I will be glad to take a look at it.

Main problem is that how i format text in file. I mean space between column & its values.

you can easily write to an ofstream like this:

double d = 5.5;
os << d;

To insert tabs, just use the escape character '\t':

cout << "TA\t" << 'B' << '\n';

As already has been said, show some code, where your problem exists.
Maybe what your "text format" currently looks like and what you want it to look like
