You can apply STL generic algorithms to a sequence of elements. They are defined in the header file . (on pre-standardized implementations, the name is used instead). Iterators are used to navigate sequences and are defined in the header file .

STL also provides several classes and algorithms that are specifically designed for numeric computations. These classes and algorithms are defined in these headers:

   // complex numbers and their associated operations  // mathematical vectors and their associated operations  // generalized numeric operations

Finally, three additional headers contain auxiliary components that are used in STL containers and algorithms, but you can also use them independently. These headers are:

 	  // operators and pairs  // function objects  // allocators and auto_ptr
