Question

void printOutput(std::string text);
void printOutput(std::string& text);

Both functions print some text out to the console, but I wanted to handle each case where:

std::string testOutput = "asdf";
output->printOutput(testOutput); // Gives the error as it can use either function

In some cases I may want to:

output->printOutput("asdf"); // Only the first function can be used

Rather new to all this, is there a way I can handle this?

Answer 1

Pass by const reference:

void printOutput(const std::string &text);

Both forms can bind to that, and you shouldn’t have to modify what you print.
