that value, decrementing highest, and going over and over again). |
So, using the ctype.h header and the isspace() function, would this be what you're getting at? (Sorry, I'm not at a computer with a compiler, so I can't test this)
while ((c = getchar()) != EOF) {
++nc;
if (isspace(c) ){
--nc;
if ((nc > 0) && (nc < MAXSIZE)) {
++arr[nc-1];
nc = 0;
} else if (nc > MAXSIZE) {
arr[MAXSIZE]++;
nc = 0;
}
}
}
