Question

C++ programming I need help finding a search word and the longestword in a data file. Example Program output Enter inputfile name data09 Enter search string ill The reformatted content of data09 is: Jack and Jill went up the hIll 2 fetch a pail of
still water. Jack fell down and broke his crown
and Jill came tumbling after! willjillbeill? # of times ill found:   6 longest word:   willjillbeill? it should not count Ill in hIllbecause the "i" is capitalized data09 is a filestream. *I am not allowed to usearrays I need to add it to my program. This is my program sofar: #include<fstream>
#include<iostream>
#include<string>
#include<iomanip>
using namespace std;
int main()
{
ifstream infile; //input filestream variable
string FileName; //variable to hold file name
int count,prevcount=0,max=50;
string word;
bool notfirst=false,firstword=true;
cout<<"Enter input file name"<<endl;
cin>>FileName;
infile.open(FileName.c_str());
infile>>word;
while(infile)
    {count=word.length();
      if(count+prevcount>max)
        {cout<<endl;
         prevcount=0;
         notfirst=false;
        }
      else
        notfirst=true;
      prevcount+=count+1;
      if(notfirst&&!firstword)
        cout<<" ";
      firstword=false;
      cout<<word;
      infile>>word;
    }
cout<<endl;
return 0;
