ifstream inFile2;
ofstream outFile1;
int mClientNumber, fClientNumber;
string mClientName;
   string fClientName;
bool atLeastOneFileNotAtEnd = true;
bool inFile1Written = false;
bool inFile2Written = false;
  
cout << "File merge processing starting." << endl;
  
inFile1.open("MaleClients.rtf");
inFile2.open("FemaleClients.rtf");
outFile1.open("MergedClients.rtf");
  
inFile1 >> mClientNumber;
   inFile1 >> mClientName;
inFile2 >> fClientNumber;
   inFile2 >> fClientName;
  
   while (atLeastOneFileNotAtEnd == true)
{
   if(inFile1.eof())
{
   if(inFile2Written == false)
{
   outFile1 << fClientNumber << " " << fClientName << endl;
inFile2Written = true;
}
   }
else if(inFile2.eof())
{
if(inFile1Written == false)
{
outFile1 << mClientNumber << " " << mClientName << endl;
inFile1Written = true;
}
}
else if (mClientNumber < fClientNumber)
{
outFile1 << mClientNumber << " " << mClientName << endl;
inFile1Written = true;
}
else
{
outFile1 << fClientNumber << " " << fClientName << endl;
inFile2Written = true;
}
  
if ((!inFile1.eof()) && (inFile1Written == true))
{

#include <iostream>

using namespace std;

int main()
{
   ifstream inFile1;
   ifstream inFile2;
   ofstream outFile1;

   bool atLeastOneFileNotAtEnd = true;
   bool inFile1Written = false;
   bool inFile2Written = false;

   cout << "File merge processing starting." << endl;
   inFile1.open("MaleClients.rtf");
   inFile2.open("FemaleClients.rtf");
   outFile1.open("MergedClients.rtf");
   if (!inFile1.is_open() || !inFile2.is_open()){
       cout<<"Errro!!! File not found!!!";
   }
   inFile1 >> mClientNumber;
   inFile1 >> mClientName;
   inFile2 >> fClientNumber;
   inFile2 >> fClientName;

   while (atLeastOneFileNotAtEnd)
   {
       if(inFile1.eof())
       {

       if ((!inFile1.eof()) && (inFile1Written == true))

       if ((!inFile2.eof()) && (inFile2Written == true))
       {

           inFile2Written = false;
       }

       if ((inFile1.eof()) && (inFile2.eof()))
       {
           atLeastOneFileNotAtEnd = false;
       }

   }

   inFile1.close();
   inFile2.close();
   outFile1.close();

   cout << "Merging Complete." << endl;

   return 0;
}

make sure the files are present and should be available for open.
