Thread: Junk Characters

You mean

Code:

for(y = 0; y < ARRAY_HEIGHT; y ++) {
    for(x = 0; x < ARRAY_WIDTH && array[x]; x ++) {
        putchar(array[x]);
    }
}

?

Wait, my previous post was probably wrong . . . .

What do you mean by stuff? Does one of your functions do it? strcpy()?

Is your string NULL-terminated?

Code:

x = 1;
printf("%s", blah[x]);

I could print it out using a For loop, however, I want the value of blah[x] to not have any junk/null characters.

I there any way to make it so that the array isn't stuffed from the back way? Any ways to alter this in code?

Arrays start at 0 for indexing, not 1. Therefore, x shouldn't be 1, because that's beyond the end of your valid array indexes. Try staying within the bounds of your array, and see if that helps not have "junk characters".


Quzah.

Post a compilable sample of code that shows your problem.

Code:

#include <stdio.h>
#include <string.h>

int main(void)
{
  char buf[1][8];
  strcpy (buf[0], "hello");
  puts (buf[0]);
  return(0);
}

Code:

for (State = NOT_INURL; c = html[i]; i++)

Are you sure that's what you want?

Well, I was thinking you meant

Code:

c == html[i]

Oh, no, I want the value of html[i] put into c so I can manipulate c, not html[i]. There must be something that's stuffing the array with characters, putting it in backwords or something like that..

Edit: Nevermind, I found the mistake. I forgot to reset the second index back to zero, after the string was null terminated.

Thanks for the help guys.

Oh . . . okay.

One other thing: you could eliminate that continue by making the ifs else ifs.
