I have a normal text file as below:

-------------------
Debdipta
1234567 8
rajat
123432 4
Kaushik
685784 7
djghkvnfj
213122 6
--------------------

I want to delete a string from this file ex:below-

---------------
Debdipta
1234567 8
Kaushik
685784 7
djghkvnfj
213122 6
--------------------

You can see that rajat and its corresponding field is deleted:

I want to do this trough C?
I can file this string and put file pointer there through following code:

C#

fseek(fp, 0, SEEK_SET);
    while(!feof(fp))
    {
        fgets(strFileMem, MAX_PATH, fp);
        fseek(fp, 0, SEEK_CUR);
        if( NULL == strstr(strName, strFileMem) )
        {
            break;
        }
    }
    int ierr = fputs("\n", fp);
    ierr = fputs("\n", fp);

Any idea what to put in fputs???

any other code?

thanks

You could try reading the file line by line writing each line out to a new file unless it's the one you want to delete. Then when you're finished, delete the original file and rename the new one to the original name

fputs outpus a string to a file, it will not just eat a string.

You should read the whole file into a buffer and do the delete operation with a char array. Then output the modified string back to the file.
