i think its not array of 1 but instead array of 2 which is 0 and 1 index. maybe 
it is because u were thinking that the last array index (in this case is 1) is 
null, but it is only applicable when handling string because string needs a 
terminated string. ex.

char tst[1];
tst[0]='g';
tst[1]='r';
printf("%s",tst); //this would print gr<and more chars here because it is not 
terminated
printf("%c=%c"); //this will print gr meaning tst[1] is alocated by 'r'

try this out.
