    Please tell me how you would use strcpy(), ... to process an integer zero-filled to five positions? Or how would you use your suggested functions to know the address value of a pointer?

    Do you really think that "formatted" in this case is the same as strcpy()? That sounds more like unformatted printing.

    If printf() is configured to emit the text to your first serial port, how would you emit text to a memory region in your flash, or on the SPI bus or on a LCD display?
