slice std::array cpp
To slice a std::array
in C++, you can use the std::array
member function std::array::slice
. Here are the steps to perform the slice operation:
- Declare a
std::array
object: Begin by declaring astd::array
object with the desired type and size. For example:
std::array<int, 5> myArray = {1, 2, 3, 4, 5};
- Define the slice range: Specify the range of elements you want to slice from the array. You can use an iterator or an index-based approach. For example, to slice elements from index 1 to 3:
std::array<int, 3>::iterator start = myArray.begin() + 1;
std::array<int, 3>::iterator end = myArray.begin() + 4;
- Perform the slice operation: Use the
std::array::slice
member function to extract the desired elements into a newstd::array
. Pass the starting and ending iterators or indices as arguments. For example:
std::array<int, 3> slicedArray = myArray.slice(start, end);
- Access the sliced elements: You can now access the sliced elements using the newly created
std::array
. For example, to print the elements:
for (const auto& element : slicedArray) {
std::cout << element << " ";
}
That's it! You have successfully sliced a std::array
