Can anyone explain why i am getting an error "no operator ">>" matches these operands" for line 167??

files do not save enum type.
I never used enums but I think write function might solve your problem.Not sure

This is coming from a noob on file handling, but I always get the same error message when I get my 'ifstream's and 'ofstream's mixed up. So you might want to double check that.

If you are reading IN data from textIn then why are you using the >> operator? Why not use something like the following?

std::string buf;
while(getine(textIn,buf)  && textIn.peak()!=EOF){
 ...
}

One you read the line into buf you use a variety of searches on the string buf to find the data you are looking for. For example, if your data is organized by line as follow.

RESIDENTS.TXT

socialSecurityNumber,latName,phoneNumber,typePhone

You might modify your while statement to the following.

std::string buf;
int pos;
while(getline(fileIn,buf){
    pos=buf.find(','); //Searching the comma separator. Pos now stores its position
	ResidentRecords[counter].socialSecurityNumber=buf.substr(0,pos);
	buf.erase(0,pos+1); //We use +1 to erase the commas as well
	pos=buf.find(','); //Find the next comma
	ResidentRecord[counter].lastName=buf.substr(0,pos);
	buf.erase(0,pos+1);
	pos=buf.find(',');
	ResidentRecord[counter].phoneNumber=buf.substr(0,pos);
	buf.erase(0,pos+1);
	/*Having no more commas we can just store the rest of buf into the struct*/
	ResidentRecord[counter].typePhone=buf;	/*You have typePhone as an enum so you might need to convert this to an int or some other data type depending on your needs./*
	counter++;
	/*The loop will now start back over with the NEXT line of data. It looks like you need to incriment counter, which you did not do here in this function.*/
}

In truth I usually do it slightly differently than what I have shown above. I nest another while loop WITHIN the one above as follow

while(getline(textIn,buf){
	while (!buf.empty()){
		//Retrieve data here	
	}
}

The two while loop method may require the use of a different data type so you may prefer not to use it.

The answer to his original problem is answered above.There is no standard operator in fstream library that takes right hand operand as enum type.

But you can save its elements by using there name as used for calling.

Try using write function for enum type(not sure about this one).It works for class and structs

I had a guy at work help me out, and he gave me this...it seems to work

void ReadAndStoreInputFile (ifstream& textIn, RecordType ResidentRecords [], int& counter)
{
	// while file is still readable, and peek does not find end-of-file
	while (textIn.good () && textIn.peek () != EOF)
	{
		// if the file contains too many lines of data, stop reading data and issue warning
		if (counter >= MAX_RESIDENTS)
		{
			cout << "Error: file contains too many lines of data" << endl;
		}
		else
		{
			// read in data from RESIDENTS.TXT
			textIn >> ResidentRecords [counter].socialSecurityNumber;
			textIn >> ResidentRecords [counter].lastName;
			textIn >> ResidentRecords [counter].phoneNumber;
			textIn >> (int&) ResidentRecords [counter].typePhone;

			counter++;
		}
		
		// read newline
		textIn.get ();
	}
}
