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