.push_back()

In C++, the .push_back() method adds an element to the end of the deque.

Syntax

dequeName.push_back(value);

• value: The element to be added to the back of the deque. It can be of any data type that the dequeName holds.

Example

The example below showcases the use of the .push_back() method:

#include <iostream>
#include <deque>

int main() {
  // Create a deque of integers
  std::deque<int> numbers;

  // Use .push_back() to add elements to the deque
  numbers.push_back(10);
  numbers.push_back(20);
  numbers.push_back(30);

  // Display the elements of the deque
  std::cout << "Deque contents: ";

  for (int num : numbers) {
    std::cout << num << " ";
  }

  std::cout << std::endl;

  return 0;
}

The above code generates the following output:

Deque contents: 10 20 30
