How to parse this data in c++?

[rustyrustyrusty]

Hello, I am doing a project where the user inputs the name of a file, (the format of the data for the file will always be the same), my instructor makes sure the files he uploads is in the same format as the one we use to make the program. The program is suppose to take the data and then print it out into a vertical histogram using *s to denote the frequency of each number. The data set looks like this;

1
1 1
2 1
3 1
3 1
4 1
4 1
5 1
5 1
6 1
6 1
5 1
5 1
4 1
4 1
3 1
3 1
2 1
2 1
1 1
1 1

Can someone please tell me how I parse this kind of data and fit it into my histogram? I can't figure out what I am doing wrong and it is the last part I need to fix for this. Thank you for any help.

  #include <fstream>

#include <iostream>

#include <string>

#include <iomanip>


using namespace std;



void OpenFile(ifstream&);

void ParseFileLines(ifstream&, int*, int*);

void CloseFile(ifstream&);

void DrawGraphs(int*, int*);

void GetAverage(ifstream&, int&);

int main()

{

	ifstream inFile;

	int speed[21];

	int incline[21];

	int average;

	OpenFile(inFile);

	ParseFileLines(inFile, incline, speed);

    CloseFile(inFile);

	DrawGraphs(speed, incline);

	GetAverage(inFile, average);
}



void DrawGraphs(int * speed, int * incline)

{

	cout << "SPEED GRAPHIC:" << endl;

	cout << "   1   2   3   4   5   6   7   8   9  10" << endl;

	cout << "---+---+---+---+---+---+---+---+---+---+" << endl;

	for (int i = 1; i < 21; i++)

	{

		cout << string(speed[i] + 3, '*');

	}



	cout << "INCLINE GRAPHIC:" << endl;

	cout << "   1   2   3   4   5   6   7   8   9  10" << endl;

	cout << "---+---+---+---+---+---+---+---+---+---+" << endl;

	for (int i = 1; i < 21; i++)

	{

		cout << string(incline[i] + 3, '*') <<endl; 

	}

}



void CloseFile(ifstream & file)

{

	file.clear();

	file.close();

}



void ParseFileLines(ifstream & file, int * speed, int * incline)
{
	{

		char line[3];

		int i = 0;

		while (!file.eof())

		{

			file.getline(line, 3, ' ');

			speed[i] = line[0];

			incline[i] = line[2];

			i++;

		}

	}

}


void OpenFile(ifstream& file)

{

	string a;



	cout << "Enter the filename" << endl;

	getline(cin, a);

	file.open((a.c_str()));



	while (!file.good())

	{

		file.clear();

		cout << "File failed to open" << endl;

		cout << "Please re-enter the pathway" << endl;

		cin >> a;

		file.open(a.c_str());

	}

}


void GetAverage(ifstream&,int&)


	{	

		const int NUM_SCORES = 21;		

		ifstream infile;
		int average;
		int sum,						
			score,						
			count;	
		    

		sum = 0;						
			

		
		for (count = 1; count <= NUM_SCORES; count++)
		{
			infile >> score; 			
			cout << setw(3) << score << setw(2) << endl;
			sum = sum + score;
		}

		
		average = sum / NUM_SCORES;

	}	

Put the code you need help with here.

anyone can help?

Can someone please tell me how I parse this kind of data

Is that not what void ParseFileLines(ifstream & file, int * speed, int * incline) does?

[rustyrustyrusty]

It is suppose to but it does not work at all. When I got to actually run my program and I upload the data file, it just gives me a error message and says the program stopped workings. But it compiles.

It has nothing to do with parsing. Its a run time error you have.

Okay I am going to use a debugger and see if i can figure out what is going on. Thank you all for the help.
