function undeclared?

[Firzin]

I'm getting an undeclared error in my main program at line 45. Can anyone find out what is causing it?

Main

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

#include "playlist.h"

using namespace std;

int main (int argc, char*argv[])
{
    ifstream fin;
    int lineCounter = 1;
    string parsedLine[NUM_OF_FIELDS];
    vector <Song> song;
    unsigned int i;
    string line;
    
    if (argc != 2)
	{
		cout <<"Wrong number of arguments.\n";
		exit(1);
	}
    //Open file specified on command line.
    fin.open (argv[1]);
    //If it cannot open the file exit the program.
    if (fin.fail())
    {
       cout <<"Could not open the input file. \n";
       exit(1);
    }
    
    getline(fin,line);
	
    while (getline(fin,line ))
	{	
		lineCounter++;
		if(! parseLine(line, parsedLine) )
		{
			cerr <<"Error: invalid line in file " <<argv[1] <<" at line " <<lineCounter <<"\n\n";
		}
		else
		{
            Song newsong(parsedline[TITLE], parsedline[ARTIST], parsedline[ALBUM], parsedline[GENRE], 
                 parsedline[SIZE],parsedline[TIME],parsedline[COMMENT]);
            song.push_back(newsong);
        }
        for (int i = static_cast <int> (ARTIST); i < static_cast<int> (NUM_OF_FIELDS); i++)
		{
			parsedLine[i].clear();
		}
  } 
  
  for (i = 0; i < song.size(); i++)
  {
      song.at(i).print(cout);
  }
  cin.get();	
  return 0;
}

Are you sure that it is line 45 of the main.cpp file? AFAICT, the problem is on line 45 of playlist.cpp, where you have the print() function incorrectly associated with class 'contact'.

Fixed it but still gives me that error.

Ah, sorry, I was convinced that was the source of the issue.

Could you post the exact error message, please? There may be some detail in it that would give the cause for it.

45 C:\Users\C.C\Documents\CS136\playlist\main.cpp `parsedline' undeclared (first use this function)

That's it.

[Schol-R-LEA]

Ah, OK, I see the issue now. On that particular line of code, you consistently mistyped parsedLine as parsedline (with the lowercase 'l') and that's what it is complaining about - as far as the compiler is concerned, parsedLine and parsedline are completely different identifiers.
