Complexity
Constant.
Example
The following code uses push_back to add several integers to a std::{{{1}}}<int>:
Run this code
#include <{{{1}}}> #include <iostream> int main() { std::{{{1}}}<int> numbers; numbers.push_back(42); numbers.push_back(314159); for (int i : numbers) { // c++11 range-based for loop std::cout << i << '\n'; } return 0; }
Output:
42 314159
