Looking for a nudge in the right direction...

Hello everyone,
I was looking for some help with a program I am currently writing. I am to be given an input file with the following format:

# of temperature readings
a time stamp followed by a temperature (note that there is one blank space between the time stamp and the temperature)
I am then to convert the time from:
YYYYMMDDHHMM (e.g. 200708201425)
to
08/20/2007 14:25.

The file will have data structured as:
2
200707211245 F70.5
200708220812 C19.97
and the output will look something like this:

BIODATA Formatted Ouput

te.mp C --- recorded on MM/DD/YYYY at 12:45
te.mp C --- recorded on MM/DD/YYYY at 08:12

I've been doing piece by piece so everything was working before I tried adding the temp. When compiling, everything goes as normal. However, when attempting to run the program it immediately freezes. I'm thinking the temp has to be addressed in a completely different manner, because of the F/C in front of it as well as the white space before it. Any idea what I'm doing wrong or any advice on what to read to address this?

Also, I cannot use arrays for this program. I am just to process each temperature as it's read in.

Here's mah code:

#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>

using namespace std;

string getYear(string date)
{
       string year = date.substr(0,4);
       
       return year;
}
string getMonth(string date)
{
       string month = date.substr(4,2);

       return month;
}
string getDay(string date)
{
       string day = date.substr(6,2);
       
       return day;
}
string getHour(string date)
{
       string hour = date.substr(8,2);
       
       return hour;
}
string getMinute(string date)
{
       string minute = date.substr(10, 2);
       
       return minute;
}
string getTemp(string date)
{
       string temp = date.substr(14,date.length());
       
       return temp;
}
int main ()
{
    int numOfReadings;
    
	ifstream inFile;
	inFile.open ("biodata.dat");
	
	inFile >> numOfReadings;

	for (int i=0; i < numOfReadings; i++)
	{
        string date;
        inFile >> date;
        
        string year = getYear(date);
        string month = getMonth(date);
        string day = getDay(date);
        string hour = getHour(date); 
        string minute = getMinute(date);
        string temp = getTemp(date);
 cout << temp << endl;         // test for temp retrieval

	
	}
	
	system("pause");
	return 0;
}

Thanks for the help and I appreciate your time!

Also, the error I receive in the cmd window is:
This application has requested the Runtime to terminate it in an unusual way. blah blah blah

It looks like you need to read that string in as a getline if you are going to have static substr methods. By using the standard insertion operator >>, you are only reading in till a whitespace, so you stopping before the last bit.

As stated above

inFile >> date; means date contains only the date part of the line not the temp so what is getTemp() trying to access when you use index 14?

Awesome, thanks a lot for pointing me in the right direction. It was originally very difficult to understand just how getline worked, however after tinkering around a bit I finally came to code that worked properly.
