Pair is the container that is present in the STL library of C++ which consists of two data elements or objects. Pair In C++ Example and Program.
Pair In C++ Example is today’s topic. PAIR is a container that is present in the STL library of C++, which consists of two data elements or objects. The pair container is a simple container defined in header consisting of two data elements or objects.
The first element in the pair is referenced as ‘first,’ and the second element is referenced as ‘second’.
Pair is heterogeneous i.e. it allows to store a variable of different data types.
Pair in C++ can be assigned, copied, and compared.
For accessing the elements, the user can use a variable name followed by a dot operator followed by the keyword first or second.
An array of objects allocated in the map are in pair by default in which all the ‘first’ elements are unique keys associated with their ‘second’ value objects.
