Program Plan Intro

Vector:

The Standard Template Library (STL) includes the collection of data types and algorithms which can be used by the programmer in their programs.

• A special data type called vector is offered by STL which is useful for standard arrays.

A vector stores the elements or values in sequence order and the values are stored in continuous memory locations.

• The subscript operator “[]” in the vector helps to read the content of each element.

Syntax:

Syntax to define a vector is as follows:

//syntax for declaring a vector with size

vector <data_type> name_of_vector(no_of_elements);

In the above line,

• The keyword “vector” represents the vector declaration.
• The “<data_type>” represents the type of data the vector can hold; the data types such as “int”, “float”, “string”, “char”, and “double”.
• The “name_of_vector” represents the name of the vector.
• The “no_of_elements” inside the brackets refers the number of elements that the vector can hold.
