I want the user to be able to input a file name and display the information within the file. I’ve used the ifstream to read the variable but it only returns an error. I implemented the error so that I could know when the program has found the file or not. I don’t know if the variable needs to be wihtin the folder of the program. Tbh i dont know how to modify it for it to work.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main(){
   cout<< "What is your first name?";
   cin >> f_user;
   cout<< "What is your last name?";
   cin >> l_user;

   string file_name= f_user + l_user + ".txt";


   ifstream inFile(file_name);

   if(inFile.is_open()){
       string c;
       while (getline(inFile, c)){
           cout<< c;
       }
   }

   if(inFile.fail()){
       cout << "User not Found"<< endl;
   }

   inFile.close();

]
