Garbage value on reading from a file using getline

Question

I am writing a small program to just get the lines from a srt file in a specific format. However I am getting a garbage value in the very first (and only that) read I do using getline. Can someone point out why am I getting this abnormal behaviour?

//Small program to get the text from the srt files.

#include<iostream>
#include<string>
#include<fstream>
#include<algorithm>
#include<vector>
#include<sstream>
#include<conio.h>

using namespace std;

void srtToTranscript(ifstream* iFile, ofstream *oFile);

int main(){
std::string file_name;
std::string transcript;

cout << "Enter srt file name (without extension)";
cin >> file_name;

ifstream iFile;
ofstream oFile;

iFile.clear();

iFile.open("data\\" + file_name+".srt");
oFile.open("data\\" + file_name + "_result.txt");
srtToTranscript(&iFile,&oFile);
cout << "Conversion done. Check in the same folder";
cout << "Press a key to exit... ";
while (!_kbhit());
char dummy = _getch();
return 0;
}

void srtToTranscript(ifstream* iFile, ofstream* oFile)
{
        int i = 1;
        std:string line;
        for (; getline(*iFile, line);)  
        {
            cout << line << endl;
            cout << to_string(i) << endl;

            if (line.compare(to_string(i)) == 0){
                getline(*iFile, line);
                i++;
                continue;
            }

            *oFile << line + ",\n";
        }
        oFile->close();
}

The problem is your ifile is not being opened successfully.

I'm seeing #include <conio.h> in your include list so I assume that you are working on Visual Studio? If you have use the default directory structure when setting up Visual Studio, then say that you have a project named: "Foo" Your .srt file needs to go here:

.../Documents/Visual Studio 20##/Projects/Foo/Foo/data/Foo.srt

When I correctly placed the file there and at the prompt I entered:

Foo

I got this output in: ".../Documents/Visual Studio 20##/Projects/Foo/Foo/data/Foo_result.txt":

00:00:00,000 --> 00:00:12,000,

One thing I'd make sure of is that your line declaration in srtToTranscript is defined:

string line

Not:

std:string line
