How do I concatenate const/literal strings in C?

Question

I\'m working in C, and I have to concatenate a few things.

Right now I have this:

message = strcat(\"TEXT \", var);

message2 = strcat(strcat(\"TEXT

You are trying to copy a string into an address that is statically allocated. You need to cat into a buffer.

Specifically:

...snip...

destination

Pointer to the destination array, which should contain a C string, and be large enough to contain the concatenated resulting string.

There's an example here as well.
