Re: When you declare an array of chars and store a string in it, where is the position of the null character \0? And what happens to the unused memory locations?

yes and you get garbage on the screen:



#include <stdio.h>


int main( void )
{
  char oye[2] = "ok";

  printf("%s\n", oye);

  return 0;
}

============= OUTPUT =============
/home/arnuld/programs/C $ gcc -ansi -pedantic -Wall -Wextra test.c 
/home/arnuld/programs/C $ ./a.out 
okHßÿ¿3.L
/home/arnuld/programs/C $ 



it *accidentally* terminated because at some random place in memory it
found the NULL ?
