22. Combining language features

• You can write many new programs by combining

  • language features, built-in types, and user-defined types in new and interesting ways.

• So far, we have

  • Variables and literals of types bool, char, int, double

  • vector, push_back(), [ ] (subscripting)

  • operators !=, ==, =, +, -, +=, <, &&, ||, !

  • functions max( ), sort( ), cin>>, cout<<

  • flow control statements if, for, while

• You can write a lot of different programs with these language features!
