Why do we use the functions fflush(stdin) and fflush(stdout) in c?
Are there any alternatives to using fflush(stdin) and fflush(stdout)?
Yes, there are alternatives like using getchar() or scanf("%*c") to clear the input buffer and using setbuf(stdout, NULL) to clear the output buffer. However, fflush() is the most commonly used function for this purpose.
