STEP 1

How it works.

You can ask the string size by size(). He counts symbols.

string word = "cat";
cout << word.size() << endl;

✦ The dot connects the string to its method.

STEP 2

The dot connects the string to its method.

string word = "cat";
cout << word.size() << endl;

✦ Compare this to the first one. Then do the cool job yourself.

IN-CLASS PRACTICE

Manually type the program from the sample. So you'll remember commands and brackets.

#include <iostream>
#include <string>
using namespace std;

int main() {
    string word = "cat";
    cout << word.size() << endl;
    return 0;
}
