The STL supports quite an interesting variety of sequence containers. Sequence containers store homogeneous data types in a linear fashion, which can be accessed sequentially. The STL supports the following sequence containers:
As the objects stored in an STL container are nothing but copies of the values, the STL expects certain basic requirements from the user-defined data types in order to hold those objects inside a container. Every object stored in an STL container must provide the following as a minimum requirement:
- A default constructor
- A copy constructor
- An assignment operator
Let's explore the sequence containers one by one in the following subsections.
