How do I pass multiple ints into a vector at once?

Question

Currently when I have to use vector.push_back() multiple times.

The code I'm currently using is

  std::vector<int> TestVector;   TestVector.push_back(2);   TestVector.push_back(5);   TestVector.push_back(8);   TestVector.push_back(11);   TestVector.push_back(14); 

Is there a way to only use vector.push_back() once and just pass multiple values into the vector?

Answer 1

You can do it with initializer list:

std::vector<unsigned int> array;  // First argument is an iterator to the element BEFORE which you will insert: // In this case, you will insert before the end() iterator, which means appending value // at the end of the vector. array.insert(array.end(), { 1, 2, 3, 4, 5, 6 }); 

Answer 2

Try pass array to vector:

int arr[] = {2,5,8,11,14}; std::vector<int> TestVector(arr, arr+5); 

You could always call std::vector::assign to assign array to vector, call std::vector::insert to add multiple arrays.

If you use C++11, you can try:

std::vector<int> v{2,5,8,11,14}; 

Or

 std::vector<int> v = {2,5,8,11,14};
