Vector

Vector(unsigned int size = 0);

Description

• Constructor
• size predefined a size of the Array

Syntax

• Vector<int> myVector;
• Vector<String> myVector;
• You can choose any type as a Vector

---

~Vector();

Description

• Deletes all saved data in the array.

Syntax

• delete &myVector;

---

void push_back(T element);

Description

• Adds an element to the array.

Syntax

• myVector.push_back(15);

---

T& pop_back();

Description

• Returns the last last element of the array.
• Deletes the last element in the array.
• Decreses the size of the array.

Syntax

• int value = myVector.pop_back();

---

unsigned int size();

Description

• Gets the size of the array.

Syntax

• unsigned int size = myVector.size();

---

void resize(unsigned int size);

Description

• Resizes the array.
• Used to make the push_back() faster.
• Reservs storage for size elements.

---

unsigned int capacity();

Description

• returns the actual size of the array which is reserved in storage.

example

• Vector<int> myVector;
• myVector.resize(5);
• myVector.size() == 0
• myVector.capacity() == 5
• When an element is pushed back the size won't increase until capacity <= size.
• myVector.push_back(1);
• myVector.size() == 1
• myVector.capacity() == 5

---

void erase(unsigned int pos,unsigned int amount = 1);

Description

• Erase a sequence of elements in the array.
• Beginning from element pos.
• From there on deletes amount elements.

Syntax

• myVector.erase(2,3); Erases the elements: [-]: [x][x][-][-][-][x][x]
• myVector.erase(2); Erases the element: [-]: [x][x][-][x][x][x][x]

---

void clear();

Description

• Clears the whole array.
• All elements get deleted.

Syntax

• myVector.clear();

---

T* begin();

Description

• Gets the pointer of the first element in the array.
• Don't use it in myVector.erase(myVector.begin());

Syntax

• int *p_int = myVector.begin();
