Step 1

The program is written in C++

check.h

#include<iostream>

#include <fstream>

using namespace std;

bool arraySortedOrNot(int arr[], int n);

bool check(char* f1)

{

int a[20];

int i=0,n1;

ifstream fin1;

fin1.open(f1);

while(!fin1.eof())

{

fin1>>n1;

a[i]=n1;

i++;

}

if(arraySortedOrNot(a,i))

{

return1;

}

else

return0;

}

bool arraySortedOrNot(int arr[], int n)

{

if (n == 1 || n == 0)

return1;

if (arr[n - 1] < arr[n - 2])

return0;

return arraySortedOrNot(arr, n - 1);

}

Merge.h

#include <iostream>

#include <fstream>

using namespace std;

void merge(char* f1,char* f2,char* f3)

{

ifstream fin1, fin2;

ofstream fout;

int n1, n2;

fin1.open(f1);

fin2.open(f2);

fout.open(f3);

fin1 >> n1;

fin2 >> n2;

while (!fin1.eof() && !fin2.eof())

{

if (n1 < n2)

{

fout << n1 << endl;

fin1 >> n1;

//fin1.ignore(5, '\n');

}

else

{

fout << n2 << endl;

fin2 >> n2;

//fin2.ignore(5, '\n');

}

while(!fin1.eof())

{

fout<<n1<<endl;

fin1>>n1;

}

while(!fin2.eof())

{

fout<<n2<<endl;

fin2>>n2;

}

fin1.close();

fin2.close();

fout.close();

}

main.cpp

#include "check.h"

#include "Merge.h"

int main()

{

char fin1[10], fin2[10], fin3[10];

cout<<"Enter the first file"<<endl;

cin>>fin1;

if(check(fin1))

{

cout<<"Enter the second file"<<endl;

cin>>fin2;

if(check(fin2))

{

cout<<"Enter the third file to store result"<<endl;

cin>>fin3;

merge(fin1,fin2,fin3);

cout<<"Two files merged successfully"<<endl;

}

if(check(fin3))

{

cout<<"The merged file is sorted"<<endl;

}
