String Operators

There are a lot of operators and functions that can work on strings. See https://en.cppreference.com/w/cpp/string/basic_string.html

We can concatenate strings using the + operator:

Listing 21 string-cat.cpp

#include <iostream>
#include <string>

int main() {

    std::string a{"this is a test"};
    std::string b{"of concatenation"};

    std::cout << a + " " + b << std::endl;

}

Note

This is an example of operator overloading, a core concept of object-oriented languages like C++.
