You are using scanf, which is liable to have problems. If it sees any input it doesn't like -- any non-numbers here -- it will not skip them. They will remain in the buffer, with scanf returning an error code every loop, and your loop will become an infinite one.
Never use scanf. Use sscanf and fgets. It won't choke on input, bad lines will just be skipped.

gets
GETS(3) Library Functions Manual GETS(3)NAME
gets, fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *gets(char *s)
char *fgets(char *s, int n, FILE *stream)
DESCRIPTION
Gets reads a string into s from the standard input stream stdin. The string is terminated by a newline character, which is replaced in s
by a null character. Gets returns its argument.
Fgets reads n-1 characters, or up through a newline character, whichever comes first, from the stream into the string s. The last charac-
ter read into s is followed by a null character. Fgets returns its first argument.
SEE ALSO puts(3), getc(3), scanf(3), fread(3), ferror(3).
DIAGNOSTICS
Gets and fgets return the constant pointer NULL upon end of file or error.
BUGS
Gets deletes a newline, fgets keeps it, all in the name of backward compatibility.
Gets is not present in the Minix-vmd C library for reasons that should be obvious. Use fgets instead.
