Dynamic array is a variable size linear data structure.
- Supports arithematic, relational and assignment operator
- Supports stream insertion operation
- Supports negative indexing (
darry[-1]returns value of last element.) - Throws out of bound errors.
- Supports Iterators.
| Name | Description |
|---|---|
push() |
Pushes an element at back of the array. |
pop() |
Pops the last elemnt out of array. |
extend() |
Push multiple elements at back using an array. |
length() |
Length of array. |
capacity() |
Capacity of array. |
DArray<int> arry(4), arry2(3, 99), arry3(arry2);
std::cout << arry << std::endl; // [ 0, 0, 0, 0 ]
std::cout << arry2 << std::endl; // [ 99, 99, 99 ]
std::cout << arry3 << std::endl; // [ 99, 99, 99 ]Negative Indexing:
DArray<int> arry(3);
arry[-1] = 42;
std::cout << arry << std::endl; // [ 0, 0, 42 ]Supports Iterators:
DArray<int> arry(5, 42);
for (auto itr = arry.begin(); itr != arry.end(); itr++) {
*itr = 2;
}
for (auto e : arry) {
std::cout << e << " ";
}
// Output: 2 2 2 2 2
