Step 3 of 6
std::string is easy
std::string does what C strings made painful:
std::string a = "de_";
std::string b = a + "dust2"; // concatenation with +
b.size(); // length (7)
b == "de_dust2"; // real comparison with ==
b[0]; // 'd'
b += "!"; // append
Your turn: read a first name and a last name, then print Hello, First Last! (N letters) where N is the number of letters in both names (not counting the space).
