      Most languages support concatenation of strings using the + operator. The only mainstream languages I can think of that don’t are PHP (which uses “.”) and low-level languages like C & C++.

        C++ does as well, doesn’t it? Though I don’t often use std::string, so I’m not sure. But every other string type I worked with had + overloaded.

          I dunno, I’ve never actually worked in C++, but I tried it out online and it didn’t seem to work.

        C++ does, but it’s not a very efficient operation. https://en.cppreference.com/w/cpp/string/basic_string/operator%2B

          Using the C++ standard library beyond the C backwards compatible parts? What devilry is this‽

          I think your link has a double encoded % at the end: %25

          The correct link is https://en.cppreference.com/w/cpp/string/basic_string/operator2B

          I ran

          #include 
          #include 
          
          int main()
          {
            std::string name;
            std::cout &lt;&lt; "you"+"me";
          }
          

          Using cpp.sh, and got the following error:

          main.cpp:7:21: error: invalid operands to binary expression ('const char[4]' and 'const char[3]')
            std::cout &lt;&lt; "you"+"me";
                         ~~~~~^~~~~
          1 error generated.
          

          edit: lemmy seems to be determined to convert my less than characters to their HTML entity codes, but the error is meant to point to the “+” sign.

            This is because your operands are const char[]. That’s not a std::string.

        JavaScript might even concatenate some integers instead of adding them just for shits and giggles.

      Only if you put “you” and “me” in quotation marks.

        It’s a variable created when the conversation started.

      The answer is NameError: ‘you’ is not defined
