I cant figure out what is wrong with this

Hello, I cant figure out what is wrong with this.

Code:

  


#include "stdafx.h"

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

using namespace std;
//#include "songs.h"


//prototypes
void getData();
void printData();


//-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

int main()
{
	int many = 0; //how many things are in the file
	string filename;
	char choice;
	
	cout <<"Please enter the filename holding the initial database: ";
	getline(cin, filename);
	cout << endl;

	getData();

	if (many > 0)
	{

		cout << "Initial DB: " << endl;
		cout << endl;
		cout << endl;
		printData();


		cout << endl;
		cout << endl;
		cout << "Please choose one: " << endl;
		cout << "1. Print out Song Times" << endl;
		cout << "2. Determine the total playing time of the playlist " << endl;
		cout << "3. Quit " << endl;
		cout << endl;

		cin >> choice;
		cout << endl;
		cout << endl;

		while (cin)
		{
			if (choice == '1')
			{
				//printData()
				cout << "Sorry, can't handle yet..." << endl;
			}

			else if (choice == '2')
			{
				//songs.two ()
				cout << "Sorry, can't handle yet..." << endl;
			}

			else if (choice == '3')
			{
			exit(1);
			}

			else 
			{
				cout << "Invalid choice -- Choose again" << endl;

				cout << endl;
				cout << endl;
				cout << "Please choose one: " << endl;
				cout << "1. Print out a list of the times of the songs " << endl;
				cout << "2. Determine the total playing time of the playlist " << endl;
	                       cout << "3. Quit " << endl;
				cout << endl;

				cin  >> choice;
			}//else

		}//while
	}//if

	else 
	{
		cout << "Empty data file -- program terminating..." << endl;

		cout << endl << endl 
			 <<"End program..." << endl << endl;
	}//else

  return 0;

}//main


//-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

void getData()
{
	ifstream
		InStream;

	 int mins;
	 int secs;
	 string filename;
	  

	 cout << endl;
	 cout << "Attempting to open the file " << filename << endl;

	 InStream.clear();
	 InStream.open(filename.c_str(), ios::in);

	 if(InStream.fail() )
	 {
		 cout << "ERROR: input file called " << filename
			  << "didn't open " << endl;
		 cout << endl;
		 cout << "Program terminating ... " << endl;
		 exit(-1);
	 } //if fail

	 while (InStream)
	 {
		 getline (InStream, mins, ':');
		InStream >> secs;
	 }
 
	 

}//getData


//-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

void printData() 
{
	int mins;
	int secs;

	cout << " Song Times " << endl;
	cout << "--------------" << endl;

	for (int i=0; i = i; i++)
	{
		cout << mins << ":" <<  secs << endl;
	}//for


}//printData

There are three errors:

error C2784: 'class std::basic_istream<_E,_Tr> &__cdecl std::getline(class std::basic_istream<_E,_Tr> &,class std::basic_string<_E,_Tr,_A> &,const
_E)' : could not deduce template argument for 'class std::basic_istream<_E,_Tr> &' from 'class std::basic_ifstream<char,struct std::char_traits<char> >'

error C2784: 'class std::basic_istream<_E,_Tr> &__cdecl std::getline(class std::basic_istream<_E,_Tr> &,class std::basic_string<_E,_Tr,_A> &,const
_E)' : could not deduce template argument for 'class std::basic_string<_E,_Tr,_A> &' from 'int'

error C2780: 'class std::basic_istream<_E,_Tr> &__cdecl std::getline(class std::basic_istream<_E,_Tr> &,class std::basic_string<_E,_Tr,_A> &)' : ex

c:\program files\microsoft visual studio\vc98\include\string(145) : see declaration of 'getline'

Any Suggestions. Thank you.

>> getline (InStream, mins, ':');

look closely at the error again:

'class std::basic_istream<_E,_Tr> &__cdecl std::getline(class std::basic_istream<_E,_Tr> &,class std::basic_string<_E,_Tr,_A> &,const
_E)' : could not deduce template argument for 'class std::basic_string<_E,_Tr,_A> &' from 'int'

getline is expecting an std::string.

Formatted input is tricky in C++, and as said above, the getline function only operates on std::string's. It can be helpful to use C's family of scanf functions for formatted input. For example: we can do this:

Code:

	int a, b;
	string line;

	getline(cin, line);
	sscanf(line.c_str(), "%d:%d", &a, &b);

	cout 
		<< "Mintues: " << a << endl 
		<< "Seconds: " << b << endl;

Output:

12:45
Mintues: 12
Seconds: 45

Thank you.
