c++c++11vectorpush-back

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

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?

Solution

  • 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};
