Question

C++ data strucs aglorithms. Please do both parts short code tasks. attach output as well, both are very similar tasks . thank you i will give thumbs up .

task 1:

Task 1 Resize a traditional arra Fill array Sam earray[10] with random integers between 1-1000 Use Dynamic Array Syntax to copy the elements sam earray[10] into newarray[20] and fill the remaining memory locations. array[10] Display values in sam Display the values in newarray[20]

Second part (similar);

Answer 1

Please find below the required solution for above problem:

#include<iostream>
#include<vector>
#include<stdlib.h>
#include<iterator>

using namespace std;
//please use c++ 11 complier

int main()
{
   //initial array delcared with 10 elements
   int array[10];

   int i;
   //initia;ized the array with random elements
   for(i=0;i<10;i++)
   {
       //rand function will generate random no between 1 and 1000
       array[i]=rand() % 1000 + 1;
   }
   //printed the old values from
   cout<<"printing from array with 10 elements : \n";
   for(i=0;i<10;i++)
   {
       cout<<array[i]<<" ";
   }
   //declared the new array of size 20
   int newarray[20];
   //using dynamic copy copied the element from old to new
   copy(begin(array), end(array), begin(newarray));

   for(i=10;i<20;i++)
   {
       //filling the rest position of array with random variables
       newarray[i]=rand() % 1000 + 1;
   }
  
//dispalying the values of new array
   cout<<"\nprinting from array with 20 elements : \n";
   for(i=0;i<20;i++)
   {
       cout<<array[i]<<" ";
   }
  
   //declared the vector of initial size of 10
   vector<int> vectorarray(10);
   for(i=0;i<10;i++)
   {
       //initialized the vector to some random values
       vectorarray[i]=rand() % 1000 + 1;
   }
   //print out the values of vector from old
   cout<<"\n\nprinting from old vector with 10 elements : \n";
   for(i=0;i<10;i++)
   {
       cout<<vectorarray[i]<<" ";
   }
  
   //resized vector to store 20 elements
   vectorarray.resize(20);
//initialized the rest place with some random values
   for(i=10;i<20;i++)
   {
       vectorarray[i]=rand() % 1000 + 1;
   }
   //displaying all 20 values from a vector
   cout<<"\nprinting from resized vector with 20 elements : \n";
   for(i=0;i<20;i++)
   {
       cout<<vectorarray[i]<<" ";
   }
   delete[] array;
   return 0;
}
