Explanation / Answer

Your getData method is having some problem...

both the variables are reading into first element only....
thats why you are getting the error while calculating lowaverage temperature.
void getdata(double t[][2], int m) {    for (int i=0; i<m; i++)    {    cout<<"enter thehighest temp for the month"<<(i+1)<<" : ";    cin>>t[i][0];    cout<<"enter thelowest temp for the month"<<(i+1)<<" : ";    cin>>t[i][0];    }    }

here is the corrected code:
#include <iostream.h>

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 yearis "<<averagehigh(temperatures, months);
    cout<<"the average low temp for the yearis "<<averagelow(temperatures, months);
    return 0;
}

void getdata(double t[][2], int m)
{
     for (int i=0; i<m; i++)
     {
         cout<<"enterthe highest temp for the month"<<(i+1)<<" : ";
        cin>>t[i][0];
         cout<<"enterthe lowest temp for the month"<<(i+1)<<" : ";
        cin>>t[i][1];
     }
}

double averagehigh(double t[][2],int m)
{
     double sum=0;
     for(int i=0; i<m; i++)
    {
        sum+= t[i][0];
    }
     return(sum/(double)m);
}

double averagelow(double t[][2],int m)
{
    double sum=0;
    for(int i=0; i<m; i++)
    {
        sum+= t[i][1];
    }
    return(sum/(double)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][0]>lowest)
    {
       lowest=t[i][1];
        ind=i;
    }
   return ind;

}
