Hi,

A newbe question...

I want to print some messages on the screen. I'm doing this:

char mymessage[] = "Hello";
dbPrint (mymessage);

This works OK - but how do I add messages together? i.e.

char mymessage[] = "Hello";
mymessage = mymessage + " world";
dbPrint (mymessage);

Thanks for any advice!

There are many C/C++ functions that can be used, like 'strcat', also you better end your strings with a termination char '\0':

Zero-termination is automatic; it's not necessary to do yourself.

As for the original question, I'd keep a buffer available to do string operations with. If you want to add two strings together, write the first one to the buffer with strcpy, then append the second one using strcat, both of which are defined in string.h:



Note that if you specify a dynamically allocated buffer to copy into, you must use the non '_s' version of these functions, or pass in the size of the buffer as the second parameter.
