Can someone explain what is mean by a function having “no return value” please. The code below is returning something, given the parameters of “Beyonce”, “Knowles” is it not? so wouldn’t that be a value?

#include

// Define introduction() here:
void introduction(std::string first_name, std::string last_name) {
std::cout << last_name << ", " << first_name << " " << last_name << “\n”;
}

int main() {

introduction(“Beyonce”, “Knowles”);

}

I did something unnecessarily longer, but it still works.

void introduction(std::string first_name, std::string last_name)
{
  std::string f_name = first_name;
  std::string l_name = last_name;
  std::cout << l_name << ", " << f_name << " " << l_name << std::endl;
}
