Normally while reading a text file we use a loop command
while((c=getchar()) != EOF)
and when it reaches the EOF the loop breaks.

Question : Is there any way that we can jump the control again to the beginning of the text file so that c=getchar() begins again???
 

Hi, I think you are going to have to clear/close the file you just read and reopen it again since it is already at eof.

No, you don't have to close the file. You can use ftell, fseek.

- ftell tells you the position of the reading point
- fseek sets the position.

If you do : seek(f0, 0, 0), then you're back to the beginning of the file.
