Text as a type

Open

Include <string> and use string for text. You can read a whole word with cin, or a full line with getline.

s.size() (or s.length()) tells you how many characters are in the string. You can index characters with s[i], starting at 0.

Two strings can be joined with +.

#include <string>

string name = "Ada";
cout << name.size() << endl;   // 3
cout << name[0] << endl;       // A
cout << name + " Lovelace" << endl;
