SOS not getting proper output

[kevinkawecki]

I have an assignment that takes an input of weather data and processes to give an output in the form of a table

It takes the input:

then I am required to make the output:

STATION_NAME ELEVATION LATITUDE LONGITUDE TPCP MNTM

AMELIA 4 SW VA US: too few readings

Here's my Code:

in.ignore(5000, '\n'); //Ignore the first line of data

while ( !in.fail() )

if ( name == namechg )
{

{

}
tempsum += temp;
tpcpsum += tpcp;
namechg = name;

oldlog = log;
totdata++;
}
if ( totdata >= 12 )
{

tempavg = fahrCon( tempavg );
tpcpavg = tpcpsum/12;
tpcpavg = inCon( tpcpavg );
out << namechg << "\t" << oldele << "\t" << oldlat << "\t" << oldlog << "\t"

}
if ( totdata < 12 && name != namechg )
{
out << name << ":\ttoo few readings" << endl;

}

namechg = name;
totdata++;
readData(in, name, ele, lat, log, tpcp, temp );

}

}

void main()
{

}

//function to inport the next line of data
void readData ( ifstream& in, string& name, string& ele, string& lat, string& log, double& tpcp, double& temp )
{

}

//function to convert the temperature to degrees fahrenheight
double fahrCon ( double& temp )
{

temp = temp * 9/5 + 32; //convert celsius to fahrenheit
return temp;
}

//function to convert millimeters to inches
double inCon ( double& tpcp )
{
tpcp = tpcp * 5/127; //convert millimeters to inches
return tpcp;
}

And it's giving the output it's giving:

STATION_NAME ELEVATION LATITUDE LONGITUDE TPCP MNTM
CULPEPER 6.1 W VA US 177.7 38.4595 -78.1136 11.3911 32

AMELIA 4 SW VA US: too few readings
AMELIA 4 SW VA US 105.2 37.3451 -77.9781 20.4396 32

I'm not sure what I am doing wrong and I have been staring at this for hours. Any help would be appreciated
