@Mohit.
You can understand by the example.
printf("indiacon\rbix");
It produce an output as bixiacon.
The main function of \r is ,it prints the string which are written in right side and count the number of character(here bix=3) and then the cursor move to the left and skip as many number of character which was read from the right side of \r(here 3).
