NEED HELP: reading file and finding average and stdv

[rosiebud492]

I keep getting stuck trying to find the average and standard deviation because i cant get my program to read the file correctly. please tell me what im doing wrong.

#include <iostream>
#include <fstream>
using namespace std;

void readData();
void calculateStats();
void saveResults();
int number;
int main()
{
readData();

return 0;
}
void readData(int)
{
ifstream inputFile;

inputFile.open("datatable.txt");
while (inputFile >> number)
{
cout << number<< endl;
}
inputFile.close();

}

I had to format your code just to be able to read it.
Youll get more help if you use code tags.

Not sure what your doing but try to change
void readData(int)
to
void readData()

It worked for me.

Ok i fixed that, im trying to find the sum and my numbers are not the same as in my data table

#include <iostream>
#include <fstream>
#include <cmath>
using namespace std;

void readData();
void calculateStats();
void saveResults();
int value=0;
int numbers=0;
int count=0;
double sum = 0;
int main()
{
	readData();

	return 0;
}
void readData()
{
	ifstream inputFile;

	inputFile.open("datatable.txt");
	while (inputFile >> value)
	{
		cout << value << endl;
		numbers++;
		sum += value;
		cout << "sum" << sum;
	}
	inputFile.close();

}
