Hi,
Sorry for asking this question here. I just thought
that this might be a platform specific issue=). I'm
reading this book(The C Programming Language 2nd
Edition by Brian W. Kernighan. Upon reading the book,
I came up with this example code. It says, it will
count the number of words, lines and characters in the
command line, until I send an EOF signal. I copied it
verbatim and tried compiling it with plain "cc
myprog.c"
It exited with errors:
word.c: In function `main':
word.c:17: error: invalid lvalue in assignment
Any idea what this means?
Thanks.
Here's the code:
#include<stdio.h>
#define IN 1
#define OUT 0
main()
{
int c, nl, nw, nc, state;
state = OUT;
nl = nw = nc = 0;
while ((c = getchar()) != EOF) {
++nc;
if (c == '\n')
++nl;
if (c == ' ' || c == '\n' || c = '\t')
state = OUT;
else if (state == OUT) {
state = IN;
++nw;
}
}
printf("%d %d %d\n", nl, nw, nc);
}
