std::deque<T,Allocator>::pop_back
void pop_back();
|
Removes the last element of the container.
Calling pop_back
on an empty container is undefined.
Iterators and references to the erased element are invalidated. It is unspecified whether the past-the-end iterator is invalidated. Other references and iterators are not affected. | (until C++11) |
Iterators and references to the erased element are invalidated. The past-the-end iterator is also invalidated. Other references and iterators are not affected. | (since C++11) |
Parameters
(none).
Return value
(none).
Complexity
Constant.
Exceptions
(none).
Example
#include <deque>
#include <iostream>
template<typename T>
void print(T const & xs)
{
std::cout << "[ ";
for(auto const & x : xs) {
std::cout << x << ' ';
}
std::cout << "]\n";
}
int main()
{
std::deque<int> numbers;
print(numbers);
numbers.push_back(5);
numbers.push_back(3);
numbers.push_back(4);
print(numbers);
numbers.pop_back();
print(numbers);
}
Output:
