reference back();		(since C++11)
const_reference back() const;		(since C++11)

Returns reference to the last element in the container.

Parameters

(none)

Return value

reference to the last element

Complexity

Constant

Example

The following code uses back to display the last element of a std::array<char>:

#include <array>
#include <iostream>
 
int main()
{
    std::array<char> letters {'o', 'm', 'g', 'w', 't', 'f'};
 
    if (!letters.empty()) {
        std::cout << "The last character is: " << letters.back() << '\n';
    }  
}

Output:

The last character is f
