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 Trims the capacity of this vector to be the vector's current size. If the capacity of this vector is larger than its current size, then the capacity is changed to equal the size by replacing its internal data array with a smaller one. An application can use this operation to minimize the storage of a vector.
