Vector Y is a container class in C++ that stores a sequence of elements. It is commonly used for dynamic arrays and allows for efficient element access and manipulation. Some examples of using Vector Y includes initializing and adding elements to the container, accessing elements by index, and resizing the container as needed.
Here are some code examples using Vector Y:
1. Initializing Vector Y with elements:
// Include the Vector Y library #include
// Create instance of Vector Y with elements std::vector myVector = {1, 2, 3, 4, 5};
2. Adding elements to Vector Y:
// Include the Vector Y library #include
// Create instance of empty Vector Y std::vector myVector;
// Push elements into the Vector Y myVector.push_back(1); myVector.push_back(2); myVector.push_back(3);
3. Accessing elements by index:
// Include the Vector Y library #include
// Create instance of Vector Y with elements std::vector myVector = {1, 2, 3, 4, 5};
// Access element in Vector Y by index int valueAtIndex2 = myVector[2];
4. Resizing Vector Y:
// Include the Vector Y library #include
// Create instance of Vector Y with elements std::vector myVector = {1, 2, 3, 4, 5};
// Resize Vector Y myVector.resize(10);
These examples use the standard Vector Y library that is included in C++.
