use single pointers only eg intx and not intx and vectors ON

use single pointers only eg. int*x and not int**x and vectors (ONE DIMENTIONAL) to answer the questions bellow. and do not use any\" malloc.h\" or similar file make a function for concatention C++ CODE ONLY

Matrix concatenation In this exercise you are invited to write a program that performs a horizontal concatenation of two n*m matrices:

Example: n =3, m = 5

Matrix a : 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Matrix b : 16 17 18 19 20 6 7 8 9 10 11 12 13 14 15 Horizontal Concatenation Matrix: 1 2 3 4 5 16 17 18 19 20 6 7 8 9 10 6 7 8 9 10 11 12 13 14 15 11 12 13 14 15

Your program should create two functions: 1) concatenate() that takes 2 vectors as parameters and return an array containing the two vectors

Example: for m =5 Vector a: 1 2 3 4 5 Vector b: 6 7 8 9 10 Concatenated array: 1 2 3 4 5 6 7 8 9 10

2) horizontalConcatenation() that takes two matrices as parameters and returns a matrix representing their concatenation. This function should use the concatenate () function.

MAKE A C++ CODE

Solution

#include<iostream>
#include<vector>
using namespace std;

int main()
{
   vector<int> concatenate(vector<int> a, vector<int> b);
   vector<int> horizontalConcatenation(int a[][5], int b[][5],int m,int n);
   vector<int> a, b,c;
   vector<int> e;
   int mat1[5][5],mat2[5][5],m,n;
  
   a.push_back(1);
   a.push_back(2);
   a.push_back(3);
   a.push_back(4);
   a.push_back(5);
   b.push_back(6);
   b.push_back(7);
   b.push_back(8);
   b.push_back(9);
   b.push_back(10);

   c = concatenate(a,b);
   cout<<\"concatinated array: \";
   for(int i = 0; i < a.size()+b.size() ; i++)
   {
       cout<<c[i]<<\" \";
   }
   cout<<\"Enter m = \";
   cin>>m;
   cout<<\"Enter n = \";
   cin>>n;
   cout<<\"Enter matrix elements for a:\";
   for(int i = 0; i < n; i++)
   {
       for(int j = 0 ; j < n ; j++)
       {
           cin>>mat1[i][j];
       }
   }
   cout<<endl;

   cout<<\"Enter matrix elements for b:\";
   for(int i = 0; i < n; i++)
   {
       for(int j = 0 ; j < n ; j++)
       {
           cin>>mat2[i][j];
       }
   }
  
   e = horizontalConcatenation(mat1,mat2,m,n);  
   cout<<\"concatinated matrix: \";

//problem in printing this array , otherwise works fine due to lack of time ,done until this
   for(int i = 0; i < n+n ; i++)
   {
       cout<<e[i]<<\" \";
   }
  
}

vector<int> concatenate(vector<int> a, vector<int> b)
{
   vector<int> c;
  
   for(int i = 0; i < a.size() ; i++)
   {
       c.push_back(a[i]);
   }
   for(int i = 0; i < b.size() ; i++)
   {
       c.push_back(b[i]);
   }
  

   return c;
}

vector<int> horizontalConcatenation(int a[][5], int b[][5],int m,int n)
{
   int c[30];
   vector<int> d, e,f,g;

   for(int i = 0; i < n; i++)
   {
       for(int j = 0 ; j < n ; j++)
       {
           d.push_back(a[i][j]);
           e.push_back(b[i][j]);
             
       }
       f = concatenate(d,e);
       d.erase (d.begin(),d.begin()+d.size());
       e.erase (e.begin(),e.begin()+e.size());
       for(int i = 0; i< f.size();i++)
       {
           g.push_back(f[i]);
       }
   }
   return g;
