Program just stops

[forsakensun12]

Im having problems with this program. It finds the average high/low, and the index high/low temperatures. But for the index high it just stops at one number even though the numbers after it is higher. Everything is right besides the index high. It gives me the index high as 79 but it should be 84 but cant find out why. Any thoughts?

Heres my input data that i have in notepad

38 27
42 29
50 35
61 45
71 54
79 64
84 69
83 68
75 61
64 50
54 42
32 32

In function indexHighTemp you have the rows and columns swapped in the array subscripts.

The same in indexLowTemp, in addition you need to set the initial value of lowestIndex to a figure bigger than any of the data, such as 999. Otherwise the initial value of 0 is the figure which is output.

This is working code
if you have any problem to understand it tell me

#include<iostream>
#include<fstream>
#include<iomanip>

const int NO_OF_MONTHS = 12;
const int rows = 12; //The rows and collums are constant
const int cols = 2;


using namespace std;

void getData( int listTemp[rows][cols]);
void averageHigh( int listTemp[rows][cols]);
void averageLow(int listTemp[rows][cols]);
void indexHighTemp(int listTemp[rows][cols]);
void indexLowTemp( int listTemp[cols][cols]);

ifstream infile;

int main()
{



double average;
int listTemp[rows][cols];


infile.open("data.txt"); //open infile

if (!infile)
{
cout << "Error opening data.txt " << endl;
return 1;
}


cout<<fixed<<showpoint; //result will show in decimal
cout<<setprecision(2);


// calls functions
getData(listTemp);
averageHigh(listTemp);
averageLow(listTemp);
indexHighTemp(listTemp);
indexLowTemp(listTemp);


// closes file
infile.close();


system("pause");
return 0;

}

void getData(int listTemp[rows][cols])
{ //reads data in both arrays

int x;
int j;


for (x=0; x < rows; x++)
{
for( j=0; j<cols; j++)
{

infile >> listTemp[x][j];

}
}
}
void averageHigh ( int listTemp[rows][cols])
{
int x=1;
double Sum = 0; //read first column and find the average
double Average;


for (x=0; x < rows; x++)
{
Sum = listTemp[x][0] + Sum;
// Average = Sum/x;
}

Average = Sum/x;



cout << "Average high for the year: " << Average << endl<<endl;


}

void averageLow ( int listTemp[rows][cols])
{
double Sum = 0; //read the second column and find the
double Average;
//average of the lows

for (int x=0; x < rows; x++)
{
Sum = listTemp [x][1] + Sum;
}
// Average = Sum/12;

Average = Sum/12;

cout << "Average low for the year: " << Average << endl<<endl;
}



void indexHighTemp ( int listTemp[rows][cols])
{
int highestIndex = listTemp[0][0];

//finds highest in the "high" column
for(int x = 0; x < rows; x++)
{
if(listTemp[x][0] > highestIndex)
highestIndex = listTemp[x][0];

}
cout << "The index high temperature is " << highestIndex <<endl<<endl;

}

{
int lowestIndex = listTemp[0][1];
//finds the lowest in the low column

for(int x = 0; x < rows; x++)

{
if(lowestIndex > listTemp[x][1])
lowestIndex = listTemp[x][1];

}
cout << "The index low temperature is " << lowestIndex << endl<<endl;
}

Thanks for the help!
