unmatching format argument for printf

Thanks Corona!
What I meant panic is to match the format arguments of printf(), especially when pointers are involved. My bad part is the not-enough-understanding of the pointer, as I did not realize my wrong catches until I saw the warnings/errors.
Go back to the original post of this thread, First, I was wondering why array worked but pointer not. After the discussion I seemed to have some ideas that when array is used, the memory is automatically allocated, but memory was only allocated to the variable address if a pointer is used, such that enough memory needs to be allocated to the pointers of the string/substring.
The second question is what the correct way is if pointer is used. (Maybe using pointer is not the correct way, but that is another story.) But this topic was distracted by other problems with sprintf() and printf() format arguments like Don's tricks.
The most difficult parts with C to me are: 1) dynamic memory allocation of pointers, 2) match the format arguments of printf() when pointers are involved. That's what I am always panic with. The critical point is still the pointer manipulation. Need more read and study. Could not find a good course around that digs C deep as I want. Neither could I find a good instruction/book on this topic yet, or too many diverse information about this for me to catch the critical points, I should say. Thanks you lots any way. Any suggestion?

pass a pointer-to-pointer, or return a pointer?

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it: (1) one is to pass a pointer-to-pointer parameter, like: int my_malloc(int size, char **pmem) { *pmem=(char *)malloc(size); if(*pmem==NULL)...

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
