HTML tags validator

[Terrorist]

Hello Everyone,

I have done this code in C to read a HTML string from the keyboard, parse the tags and store them into a stack, then print it out.

Now I am trying to take of the Closing Tags from the stacks (aka. /html) and store them into another array.However, I have a problem with that. Could you please help me in this, I have commented the code where it SHOULD copy the closing tags to another array.

#include <stdio.h>
#define B_OPEN '<'
#define B_CLOSE '>'
#define BRACKET_MAX 10
#define B_CHAR_MAX 7

char bracket[BRACKET_MAX][B_CHAR_MAX];
int diagnosis;
signed char bracket_nr, close_nr;
