Question

Indexing Arrays & Scalar Operations

Create a new array called “myShortArray” that contains the 1^st, 3^rd, and 5^th elements of the array “myArray” as defined below using the indexing method.

     myArray = [1, 2, 3, 4, 5, 6];

Answer 1

#include<iostream>
using namespace std;
int main()
{
    //DECLARE THE ARRAYS
    int myShortArray[3],myArray[6]={1,2,3,4,5,6};
    int i,j;
    //loop to scan each element of myArray
    for(i=0,j=0;i<6;i++)
    {
       if(i%2==0) //check the odd position elements. Since array atarts with 0 index so the index with even number will be the odd position element
       //if you need to store the odd index element then the condition will be
       //if(i%2!=0)
       {
           myShortArray[j]=myArray[i];//assign the myArray element to myShortArray
           j++;
           }
   }
   //display the elements of myArray
   cout<<endl<<"Elements of myArray : ";
   for(i=0;i<6;i++)
   cout<<" "<<myArray[i];
   //display the elements of myShortArray
   cout<<endl<<"Elements of myShortArray : ";
   for(i=0;i<3;i++)
   cout<<" "<<myShortArray[i];
  
}

output
