Unlike Java, in C++ strings can be compared directly using the == sign.

if (s1 == s2) {
    cout << "Your string matches my first string, " << s1 << endl;
}

Similar to other languages, strings will only match if each character matches exactly, including case.

For example Hello will match to Hello, but not hello.
