beginner's question

I am looking to create a string terminated with a carriage return that I can then send over a SPI transfer. How do I create this string?

Code:
const char error_txt[16] ={"USART overflow\r"};
                                           ^
                                           |
                                           carriage return


note: error_txt[16] ---- 16=14(string) + 1 (\r) + 1 or string termination
also note that sometimes you will need a carriage return line feed

Code:
const char error_txt[17] ={"USART overflow\n\r"};
                                           ^
                                           |
                                           line feed
