Examples
Vector < int > intVector;
int arrayOfInts[11];  // declares an array of ints with 11 positions

void setup() {
  Serial.begin(9600); 
  pinMode(48, OUTPUT);  // turn ON wiring hardware LED
  digitalWrite(48, HIGH);
  
  for(int i=0; i<10; i++) {  // add 255 elements from 0 to 254
    intVector.addElement(i);
  }
    
  intVector.copyInto(arrayOfInts);  // copy the Vector content into an array

  Serial.print("The arrayOfInts elements are: ");
  for(int i=0; i<10; i++) {  // print all all elements in the array
    Serial.print(arrayOfInts[i], DEC);
    Serial.print(" ");
  }
  Serial.println();
  
  Serial.print("The vector's capacity is: ");
  Serial.println(intVector.capacity(), DEC);  // print the vector's capacity
  intVector.ensureCapacity(20);
  Serial.print("now the vector's capacity is: ");
  Serial.println(intVector.capacity(), DEC);  // print the vector's capacity
  
  Serial.print("The vector's size is: ");
  Serial.println(intVector.size(), DEC);  // print the vector's size
  intVector.setSize(5);
  Serial.print("now the vector's size is: ");
  Serial.println(intVector.size(), DEC);  // print the vector's size
 
  Serial.print("The vector's capacity is: ");
  Serial.println(intVector.capacity(), DEC);  // print the vector's capacity
  intVector.trimToSize();
  Serial.print("now the vector's capacity is: ");
  Serial.println(intVector.capacity(), DEC);  // print the vector's capacity  
}


void loop() {

}

Description Sets the size of this vector. If the new size is greater than the current size, new null items are added to the end of the vector. If the new size is less than the current size, all components at index newSize and greater are discarded.
Syntax

Parameters
size int: the new size of this vector
