Hello,
I'm attempting to learn C through the K&R book and am having some trouble with Exercise 1-13 at the moment. I'm just attempting to do a simple horizontal graph and can't figure out why this isn't working correctly. It seems to be ignoring my first "if" statement and just counting spaces/new lines/tabs into the current array index. It never increases the index.
Any thoughts? Thanks for your help!
#include <stdio.h>
main()
{
int c, i, j, k;
int lword[20];
j = 0;
for(i = 0; i <= 20; ++i)
lword[i] = 0;
while((c = getchar()) != EOF) {
if(c != ' ' || c != '\t' || c != '\n')
++lword[j];
else
++j;
}
for(i = 0; i <= 20; ++i) {
printf("lword[%d] = ", i);
for(k=0; k <= lword[i]; ++k)
putchar('|');
printf("\n");
}
}Here's the typical result:

This is a test. One Two Three.
