hi all

i am using VC++ editor. Can anyone tell me how to insert sleep in my program? i have tried sleep(). but it is giving an warning

'sleep' undefined; assuming extern returning int.

Sample code to help you

#include <stdio.h>

int main()
{
FILE *read, *write;
char Buffer[BUFSIZ];

if( ( read = fopen("x.txt", "r") ) == NULL )

you can use fgets()

first read the file line by line. copy the line content into a string. now use strtok () function to seperate the copied string contends.use atoi() function to tgake the numbers out.

ya thanks! but wht abt multiple entries? suppose i have checked the first entry in [MARKS] and want to check the next, how to proceed for that?

a new problem ... when i am opening the new file it doesnot have anything. if i take to write only one parameter, like [MARKS] Physics=60
it will be written, but if i try to write multiple things...

i think i nearly got it. thanks

i thnk fprintf() is a better option

by trying the way as suggested by u, shall i use fputs to write the string to new file. for reading from the file and putting to string i am using fgets()

Is there any provision to delete some part of file?

i havn't given any of the code. which code r u talking abt?

i am able to extract from file. For eg lets take [Marks] Physics = 60
i am able to extract upto =60, but nw my problem lies that i am not able to replace with new value. how do i do that?

no i haven't and want help in this regard

i want to modify the current values. i feel i should first read the file upto some size into a buffer then in that buffer search for Marks (strstr). after that agn search for Physics in the same way...
