create array pointer c++ code example

Example: arrays and pointer in c++

#include<iostream>
int main()
{	
  // three ways to enter the values of arrays 
  int array[] {1,2,3};
  
  // Array subscript notation
  std::cout<<array[0]<<std::endl;// 1 
  std::cout<<array[1]<<std::endl;// 2
  std::cout<<array[2]<<std::endl;// 3
  
  // Pointer subscript notation
  int *array_ptr ={array};
  std::cout<<array_ptr[0]<<std::endl;//1
  std::cout<<array_ptr[1]<<std::endl;//2
  std::cout<<array_ptr[2]<<std::endl;//3
  
  //Array offset notation
  
   std::cout<<*array<<std::endl;//1
   std::cout<<*(array+1)<<std::endl;//2
   std::cout<<*(array+2)<<std::endl;//3
  
  //Pointer offset notation
   std::cout<<*array_ptr<<std::endl;//1
   std::cout<<*(array_ptr+1)<<std::endl;//2
   std::cout<<*(array_ptr+2)<<std::endl;//3
    
    
   return 0;
