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?
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};
