How can I destroy a character array?

[Invincible]

I just want to release or destroy the contents of string[] and reset it back to its original state so my if statements will prove false.


int main()

{


int random_number;
float count = GetTickCount();
char string[7];
bool end = false;



while(end != true)
{
srand(GetTickCount());
random_number = rand()%20 + 1;

printf("\nType \"roll\" and hit <ENTER> to roll a");
printf(" random number, or to quit.\n\n");

fgets(string, 7, stdin);

if(strlen(string) > 5)
{
_flushall();

//(release contents of string[])

printf("true");
}

if(strnicmp(string, "exit", 4)==NULL)
{
printf("\nExiting...\n\n");
end = true;
_flushall();
exit(0);
}

if(strnicmp(string, "roll", 4)==NULL)
{
printf("\n%.0f\n\n", count);
printf("%i\n", random_number);
}


}

return 0;
}


-- Well I solved it by using a bool value and a conditional && statement, but I'd still like to know how to destroy a character array. --

you could try.....

string[0] = '\0'; /* note single quotes*/
or
strcpy(string, "\0"); /* double quotes */

these will set first element in string to null character. Equivalent I suppose of string = NULL;

Thanks. I'm still new, sometimes I get lost in all the functions. Your help is greatly appreciated.

If you want to fully clear the string, try
memset ( string, '\0', SIZE );

You rule Prelude. That's exactly what I want to do. Thanks.
