create int array code example

Example 1: java how to initialize an array

int[] arr = new int[10];	//Can hold 10 elements

Example 2: how to initialize array in java

int[] arr = new int[5];	 // integer array of size 5 you can also change data type

Example 3: array declaration c++

int foo [5];

Example 4: number of elements in c++ array

#include <iostream>
using std::cout;

int a[] = { 1, 2, 3, 4, 5 };
int counta()
  {
  return sizeof( a ) / sizeof( a[ 0 ] );  // works, since a[] is an array
  }

int countb( int b[] )
  {
  return sizeof( b ) / sizeof( b[ 0 ] );  // fails, since b[] is a pointer
  }
