Question

C++:

modify the following code so the names of the month are listed to the left of the high and low temperature readings and label the two columns of numbers as high (the one on the left) and low (the one on the right). Numbers are already in order so all that is needed is the months' names in order from top (jan.) to bottom (dec.)

code:

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

const int NO_OF_MONTHS = 12;

void getData(int twoDim[NO_OF_MONTHS][2], int rows);
int averageHigh(int twoDim[][2], int rows);
int averageLow(int twoDim[][2], int rows);
int indexHighTemp(int twoDim[][2], int rows);
int indexLowTemp(int twoDim[][2], int rows);

void displayMatrix(int twoDim[][2], int);

ifstream inFile("weather.txt");
ofstream outFile("weather.out");

int main()
{

int hiLowArray[NO_OF_MONTHS][2];

int indexHigh;
int indexLow;

getData(hiLowArray, NO_OF_MONTHS);

displayMatrix(hiLowArray,NO_OF_MONTHS);

cout << "\nAverage high temperature: "
<< averageHigh(hiLowArray, NO_OF_MONTHS) << endl;
outFile << "\nAverage high temperature: "
<< averageHigh(hiLowArray, NO_OF_MONTHS) << endl;

cout << "\nAverage low temperature: "

indexLow = indexLowTemp(hiLowArray, NO_OF_MONTHS);
cout << "\nLowest temperature: " << indexLow << endl;
outFile << "\nLowest temperature: " << indexLow << endl;

return 0;
}
