如何一次将多个整数传递给一个向量?

2021-12-21 00:00:00 vector c++ c++11 push-back

目前当我必须多次使用 vector.push_back() 时.

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

我目前使用的代码是

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

有没有办法只使用 vector.push_back() 一次并且只将多个值传递给向量?

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

推荐答案

尝试将数组传递给向量:

Try pass array to vector:

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

您可以随时调用 std::vector::assign 将数组分配给向量，调用 std::vector::insert 添加多个数组.

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

如果你使用 C++11，你可以试试:

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

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

或

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