Question

This is the assignment:
"Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and the highest and lowest temperatures for the year. Your program must consist of the following functions:
a) Function getData: This function reads and stores data in the two-dimensional array.
b) Function averageHigh: This function calculates and returns the average high temperature for the year.
c) Function averageLow: This function calculates and returns the average low temperature for the year.
d) Function indexHighTemp: This function returns the index of the highest high temperature in the array.
e) Function indexLowTemp: This function returns the index of the lowest low temperature in the array."

My teacher gave us some data and wants us to input it using a file. My question is, how should I write the input file to get each temperature into its correct slot in the array? Also, am I inputting the file correctly? Thanks.

What I have so far.

#include <iostream>

#include <fstream>

using namespace std;

const int months = 12;

void getData(double [][ 2 ], int);

double averageHigh(double [] [ 2 ], int);

double averageLow(double [] [ 2 ], int);

int indexHighTemp(double [] [ 2 ], int);

int indexLowTemp(double [] [ 2 ], int);

int main()

{

double temperatures[months][2];

getData(temperatures, months);

cout << " The average high temp. for the year: "

<< averageHigh(temperatures, months) << endl;

cout << " The average low temp. for the year: "

<< averageLow(temperatures, months) << endl;

cout << " Index of highest temp. for the year: "

<< indexHighTemp(temperatures, months) << endl;

cout << " Index of lowest temp. for the year: "

<< indexLowTemp(temperatures, months) << endl;

system("PAUSE");

return 0;

}

void getData(double t[][2], int m)

{

int i;

ifstream inFile;

ofstream outFile;

inFile.open("tempsFile.txt");

if (!inFile)

{

cout << "Cannot open input file."

<< endl;

}

for (int i=0; i<m; i++)

inFile >> t[i][0];

cout << endl;

inFile >> t[i][1];

cout << endl;

}

double averageHigh(double t[] [2], int m)

{

double sum = 0;

for (int i=0; i<m; i++)

sum += t[i][0];

return (sum/m);

}

double averageLow(double t[][2], int m)

{

double sum = 0;

for (int i=0; i<m; i++)

sum += t[i][1];

return (sum/m);

}

int indexHighTemp(double t[][2], int m)

{

int ind = 0;

double highest = t[0][0];

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

if (t[i][0] > highest)

{

highest = t[i][0];

ind = i;

}

return ind;

}

int indexLowTemp(double t[][2], int m)

{

int ind = 0;

double lowest = t[0][1];

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

if (t[i][1] < lowest)

{

lowest = t[i][1];

ind = i;

}

return ind;
