Lab 2 homework

I have a lab for school above are my materials. So far I have:

#include <iostream>
#include <iomanip>
#include <string>
#include <vector>
#include <playlist.h>
#include <fstream>
#include <stdlib.h>

using namespace std;

void readLine(vector<string> playlist);
int totalTime();
void displayData();

int main()
{
	vector<string> playlist;
	open("Playlist.txt");

	readLine(playlist);
	totalTime();
	displayData();

	system("pause");

	return 0;
}
void readLine(vector<string> playlist)
{
	string currentline;
	int i = 0;
	while (getline("Playlist.txt", currentline) && !empty(currentline))
	{
		getline("Playlist.txt", playlist[i]);
		i = i + 1;
	}
}
int totalTime() 
{

}
void displayData()
{

}

If someone could fix the two errors under "getline" and help me proceed I would deeply appreciate it!!!

Here is how you can read the file into a vector.

#include <iostream>
#include <fstream>
#include <vector>
#include <string>

using namespace std;

void readLine(vector<string> &playlist);

void main(void)
{
  vector<string> input;
  
  readLine(input);
  for (int i=0; i < input.size(); i++)
    cout << input[i] << endl; 

  system("pause");
}

void readLine(vector<string> &playlist)
{
   ifstream src("Playlist.txt");

  if (!src)
  {
    cerr << "Error opening file";
    exit(EXIT_FAILURE);
  }

  string buffer;
 
  while (src)
  {
    getline(src, buffer);
    playlist.push_back(buffer);
  }
}

You should also consider using alternatives for system() in your programs.
Something like:

#include <conio.h>

int main(){
	/*
	Your code
	*/

	// Here instead of using system("pause") use:
	_getch();	// getch() is deprecated
	return 0;
}

@AcarX

_getch() works only on windows, system is standard.

He could use getchar() instead. There're also helper functions for linux if he doesn't want to press enter.

Yes getchar could be an alternative.
