Yes, the correct declaration should be :
char x[]="Heino";
because the variable you can modify is yet the character table, and
not the pointer to a static chain.
It should be easy to upgrade, unless you do something like
x = "another chain";
further in the program... In this case, x must be a pointer and the
first declaration should be used (char *x;) !
