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

I ran
#include
#include
int main()
{
std::string name;
std::cout << "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 << "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.
