    Question Problems with "char*"... Please help

    I have some troubles with char * (pointer to char)...

    #1. Is the declaration

    // codes
    char* psz = "SAMPLE 1";
    // end of codes

    is equivalent to

    // codes
    char psz[] = "SAMPLE 1";
    // end of codes

    ?

    #2. And are the following codes bad ?

    // codes
    char* psz;
    psz = "SAMPLE 2";
    // end of codes

    The second codes (#2) seem to write data on out-of-services area, don't they ?

    Thanks in advance for your helps.

    Regards.

    These are coding technically the same thing. The addressing in memory is different.

    > char* psz;
    > psz = "SAMPLE 2";

    Works fine. You set the pointer psz to point to the begin of the constant c-style string.
    Making error is human, but for messing things thoroughly it takes a computer
