Adding to a variable

ok, can figure out how things, has me beat

so, starting char, string, int etc. containing example "abc" or "123" , want add "d" or "4" leaving variable "abcd" or "1234" respectively

how done? or heading in wrong direction?


if more explanation needed i'll try tell have loosely planned, @ stage loose i'm not entirely sure myself...

this i'm trying figure out (so can build url sent server using wiznet ethernet module).

what append / concat operator arduino language?

// doesn't work
serial.println("abc" . "d");

// neither this
serial.println("abc" + "d");

thanks!
