Question

I need to add something to this C++ program.Additionally I want it to remove 10 words from the printing list (Ancient,Europe,Asia,America,North,South,West ,East,Arctica,Greenland)

#include <iostream>
#include <map>
#include <string>
#include <cctype>
#include <fstream>
#include <iomanip>

using namespace std;
void addWord(map<std::string,int> &words,string s);
void readFile(string infile,map<std::string,int> &words);
void display(map<std::string,int> words);
  
int main() {
// Declaring variables
std::map<std::string,int> words;
  
  
//defines an input stream for the data file
ifstream dataIn;

  
string infile;
cout<<"Please enter a File Name :";
cin>>infile;
readFile(infile,words);
  
display(words);

  
return 0;
}
void readFile(string infile,map<std::string,int> &words)
{
string s;
//defines an input stream for the data file
ifstream dataIn;
//Opening the input file
dataIn.open(infile.c_str());
//checking whether the file name is valid or not
if(dataIn.fail())
{
cout<<"'"<<infile<<"' File Not Found **";
exit(0);
}
else
{
//counting how many words in the file
while(dataIn>>s)
{
addWord(words,s);
}
dataIn.close();
}
}
void addWord(map<std::string,int> &words,string s)
{
char c;
string str="";
for(unsigned int i=0;i<s.length();i++)
{
c=s[i];
if(isalpha(c))
str.push_back(std::toupper(c));
}
++words[str];
}
void display(map<std::string,int> words)
{

cout<<"---------------------"<<endl;
cout<<"Word Counter Summary "<<endl;
cout<<"---------------------"<<endl;
cout<<"\nWord\t\tCount"<<endl;
cout<<"------\t\t-----"<<endl;
  
for(std::map<std::string,int>::iterator iter = words.begin(); iter!=words.end(); ++iter)
{
cout<<setw(16)<<left<<iter->first<<setw(5)<<right<<iter->second<<std::endl;
}
  
}
