minus-squareZagorathlinkfedilinkEnglish32•2 years agoMost 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++.
minus-squareVanillaGorillalinkfedilink24•2 years agoJavaScript might even concatenate some integers instead of adding them just for shits and giggles.
minus-squareRikudou_Sagelinkfedilink8•2 years agoC++ 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.
minus-squareZagorathlinkfedilinkEnglish2•2 years agoI dunno, I’ve never actually worked in C++, but I tried it out online and it didn’t seem to work.
minus-square@meteorswarm@beehaw.orglinkfedilinkEnglish4•2 years agoC++ does, but it’s not a very efficient operation. https://en.cppreference.com/w/cpp/string/basic_string/operator%2B

minus-squareZagorathlinkfedilinkEnglish2•edit-22 years agoI 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.
minus-square@meteorswarm@beehaw.orglinkfedilinkEnglish1•2 years agoThis is because your operands are const char[]. That’s not a std::string.
