std::string and concatenation
This code joins the text Hello, and the text Ada using the + sign and prints the result. Press Run to see the combined greeting.
Why this works
C++ text lives in the string type, which comes from the <string> header (usually written std::string, but using namespace std; lets you drop the std:: prefix). Unlike a raw C-style character array, std::string manages its own memory, so it can grow, shrink, and be compared with == without you writing any low-level bookkeeping code.
The + operator joins (concatenates) two strings into a new one. This is the same + symbol used for adding numbers, but C++ figures out from the types involved that you mean "glue these pieces of text together" rather than "add these numbers."
