Is that what you tried and got all those errors? It looks most correct for what you seem to be trying to do. It's a pointer. Initialize it to 0 just in case.
Next you need to see what code sits on the line number it whines about, if it still does. I suspect the error messages point to all the lines where you are trying to assign something to msg and that's what you tinker. I can't tell off the top of my head at this hour what's it supposed to read for what you are doing there. I assume you are trying to assign the other array pointers to the msg one, so do that.
It's only going to work if twitter.post(msg) accepted a char pointer. I can see it takes a const char pointer judging by the error message. Well, see what the compiler tells you anyways without making too many changes at once between each compilation.
Another thing, if you end up getting a whole bunch of text posted (all of the strings), you probably need a null ending character \0 at the end of the string of characters. Or maybe not, I forget as I rarely have to deal with char arrays in C these days. Can you find out and post your findings?

Up to a point, people will be willing to help, but if you start just posting garbage that has been pointed out before, they'll get bored and drift away.

this is still bad assigned pointer, but i dont know how to assing a char pointer to a char variable, sorry for that
