Cout doesn't print on display (console) - c++

Question

so i have a code that's supposed to find a string of characters in a certain .txt file, if the input is in the file, it says "yey i found it" but when it isnt, its supposed to say "didnt find anything", but it just skips that step and ends.
I'm a beginner so sorry for any obvious mistakes.
#include <stdio.h>
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(void)
{
setlocale(LC_ALL, "");
string hledat;
int offset;
string line;
ifstream Myfile;
cout.flush();
cout << "Welcome, insert the string to find in the file. \n \n \n" << endl;
cin.get();
cout.flush();
Myfile.open("db.txt");
cin >> hledat;
if (Myfile.is_open())
{
while (!Myfile.eof())
{
getline(Myfile, line);
if ((offset = line.find(hledat, 0)) != string::npos)
{
cout.flush();
cout << "Found it ! your input was : " << hledat << endl;
}
}
Myfile.close();
}
else
{
cout.flush();
cout << "Sorry, couldnt find anything. Your input was " << hledat << endl;
}
getchar();
system("PAUSE");
return 0;
}

Answer 1

There are three possible cases.
The file was not successfully opened.
The file was successfully opened, but the string was not found.
The file was successfully opened, and the string was found.
You have a printout for cases 1 and 3, but not 2.
By the way, your loop condition is wrong. Use the result of the call to getline, which is the ostream object itself after the read attempt.
while (getline(MyFile, line))
{
...
}
The loop will terminate upon an unsuccessful read attempt, which will happen after you read the last line. The way you have it, you will try to read after the last line, which will be unsuccessful, but you will still try to process that non-existent line because you don't check eof until the loop starts over.

Answer 2

Just comment out //cin.get(); , you dont need it.
Output:
Welcome, insert the string to find in the file.
apple
Found it ! your input was : apple
Other than that, it works like a charm.
Corrected code:
#include <stdio.h>
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(void)
{
setlocale(LC_ALL, "");
string hledat;
int offset;
string line;
ifstream Myfile;
cout.flush();
cout << "Welcome, insert the string to find in the file. \n \n \n" << endl;
//cin.get(); <----- corrected code
cout.flush();
Myfile.open("db.txt");
cin >> hledat;
if (Myfile.is_open())
{
while (!Myfile.eof())
{
getline(Myfile, line);
if ((offset = line.find(hledat, 0)) != string::npos)
{
cout.flush();
cout << "Found it ! your input was : " << hledat << endl;
}
}
Myfile.close();
}
else
{
cout.flush();
cout << "Sorry, couldnt find anything. Your input was " << hledat << endl;
}
getchar();
system("PAUSE");
return 0;
}
