Our social interaction in a nutshell

Should have used python. The answer is youme.

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++.

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

R uses paste0() for some reason

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‽

Zagorath@aussie.zone · vor 3 Jahren

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.

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

The answer is NameError: ‘you’ is not defined

Square Singer@feddit.de · vor 3 Jahren

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