In earlier Explorations, you used quoted character strings as part of each output operation. In this Exploration, you will begin to learn how to make your output a little fancier by doing more with strings. Start by reading Listing 4-1.

import <iostream>;

int main()

{

   std::cout << "Shape\tSides\n" << "-----\t-----\n";

   std::cout << "Square\t" << 4 << '\n' <<

                "Circle\t?\n";

}

Listing 4-1.

Different Styles of String Output

Predict the output from the program in Listing 4-1. You may already know what \t means. If so, this prediction is easy to make. If you don’t know, take a guess.
