    C++ Memory Management: What is the difference between 'const char*' and 'char*const'

    Q: What is the difference between 'const char*' and 'char*const'?


    char* const
    declares a constant pointer which has both read and write access to a character (or character array). The pointer itself is a constant and you can not change it. Like all other constant variables, you must initialize it with a constant value at the same time when it is declared:

    char buffer[80];
    char* const pBuffer = buffer;
    const char*
    declares a pointer to a constant character (or a constant character array). The pointer can be changed, but the character (or array) to which it points can not be changed.
