have problem using C programming in writing data into a text file!

hello everybody! i have a problem using C in writing data into a text file.
actually i can writen the data into the text file already by using the code:
___________________________________________
fprintf(filename,"bil \tname \tsalary \tO.T \t total");
while(!EOF)
fprintf(filename,"%d \t%c%c%c \t0.2%f \t0.2%f \t0.2%f",bil,name[0],name[1],name[2],salary,ot,total);
_________________________________________________

the problem i facing is the data was not properly arrange. for example:

bil name salary O.T total
1 mch 10.00 10.00 20.00
2 efg 20.00 20.00 40.00
3 jkl 100.00 100.00 200.00
4 opq 400.00 100.00 300.00

the problem occur when the value of salary, O.T and total is more than hundred and even thousand. what code must i write in order to get this result :

bil name salary O.T total
1 mch 10.00 10.00 20.00
2 efg 20.00 20.00 40.00
3 jkl 100.00 100.00 200.00
4 opq 400.00 100.00 300.00
5 mnb 1000.00 500.00 1500.00

which is nice and easy to read.

thankz,

after looking at my posting, i found that the data was not display like what i type in the first place.so i have to explain a litter bit more so that you all will know what exactly i'm trying to say.
i want my data to arrange in 5 colums. example for 3th colum:
_______________
salary
100
10
300
900
1200
_________________
and the 4th colum
_________________
O.T
100
20
400
200
_________________


but some of the data did not start at it own colums. this happend when the "float" value is more that hundred or even more.
i hope you all understand what am i trying to say here.

thankz again,
gechin

Well...I do not know it this will fix all of your problems since I took only a quick look but the above line should be...

Code:

---

fprintf(filename,"%d\t%c%c%c\t%0.2f\t%0.2f\t%0.2f",bil,name[0],name[1],name[2],salary,ot,total);

A common mistake when looking at tab-delimited files is tab settings. If you are looking at your file in a text editor that has the tabs set to every 8 characters, for example, then putting a value that's 8 characters long will cause the remaining values in the row to be right-shifted by one column.

If you're not sure, try opening it up in Excel or change your tab settings to be really big.

well thank for the solution that you all give. i have found a more simple way to solve it. That is:

fprintf(filename,"%d \t%c%c%c \t8.2%f \t8.2%f \t8.2%f",bil,name[0],name[1],name[2],salary,ot,total);


that is replace the 0 with an integer such as 8. this will allocate 8 space for us to fill in our value.
