find the length of an array code example

Example 1: length of array in java

arr.length;

Example 2: length of array c++

// array::size
#include <iostream>
#include <array>

int main ()
{
  std::array<int,5> myints;
  std::cout << "size of myints: " << myints.size() << std::endl;
  std::cout << "sizeof(myints): " << sizeof(myints) << std::endl;

  return 0;
}

Example 3: get length of array

// In Javascript
var x = [1,2,3];
console.log(x.length);

Example 4: java get size of array

arrayname.length

Example 5: length of each number in array in c++

const int SIZE = 9;
	int arr[SIZE], arr2[SIZE];
	cout << "Enter numbers: \n";
	for (int i = 0; i < SIZE; i++)
		cin >> arr[i];
	for (int i = 0; i < SIZE; i++)
		cout << arr[i] << "\t";
	cout << endl;
	
	int count, number;
	for (int i = 0; i < SIZE; i++)
	{
		count = 0;
		number = arr[i];
		do
		{
			++count;
			number /= 10;
		} while (number);
		arr2[i] = count;
	}
	for (int i = 0; i < SIZE; i++)
		cout << arr2[i] << "\t";
	cout << endl;
