1. What is the answer the of the question, "Enter the name your file"?
#include<bits/stdc++.h>
#include<fstream>
#include <iostream>
#include<cstdlib>
#include<string.h>
using namespace std;
int c=0;
ifstream fin;
int strcmp_ncase(string s1, string s2)
{
transform(s1.begin(),s1.end(),s1.begin(), ::toupper);
transform(s2.begin(),s2.end(),s2.begin(), ::toupper);
if(s1 == s2)
return 1;
else
return 0;
}
int main()
{
cout<<"Welcome to the Name Searching Programn";
char fil[100];
cout<<"Please enter the name your file: ";
cin>>fil;
fin.open(fil);
while(fin.fail())
{
cout<<"I'm sorry, I could not open " << fil << "Please enter another name: ";
cin>>fil;
fin.open(fil);
}
cout << "File" << fil << "opened successfullyn";
getchar();

2. string search;
cout<<"What name would like to find in the file? ";
getline(cin, search);
int flag = 0;
while(!fin.eof())
{
string temp;
c++;
getline(fin,temp);
int x = strcmp_ncase(search,temp);
if(x == 1)
{
cout <<""<< temp << "is the"<<c<<"rd name in the file"<<endl;
flag = 1;
}
}
if(flag == 0)
cout<<search<<"name not found in the filen";
fin.close();
cout<<"Thank you for using he NSPn";
return 0;
}
