    string literal assignment

    Can string literals be used for assignment other than in an initializer?
    Code:
    int main( void ) {
    char *p = "foo";
    p = "bar";
    }
    (disregarding the loss of static storage) even with -Wall, this compiles with no warnings/error; though I could have sworn I had read somewhere in 9899 they could be used for initialization only...

    It depends. This code assigns the address of a string literal to a pointer (which really should be const char*), so it is fine.
    However, trying to assign a string literal to a buffer, eg:
    char foo[] = "Hello World!";
    This can only be done with initialization.
