Payroll Class with vectors

Ion93 (8)
Hey guys I'm writing a Payroll class program to calculate gross pay

Write a program that processes Payroll objects. The program should read the
employee surname,number of hours worked,and their hourly pay-rate from a file

The file is below.

So the part im currently having trouble with is writing a function to read in the data from the file into a vector so i can manipulate the vector and display my end results. Any help on how i can fix this would be great thank you!

Seems like your problem is that you're trying to read from the file directly to the vector.
try something like: 
1
2
3

void readFunction( ifstream &inFile, vector<Payroll> &list )
{
	string name;
	double hours;
	double rate;
	double count;      // count number of items in the file
	Payroll temp;

	if( inFile )
	{
		double count;      // count number of items in the file

		// read the elements in the file into a vector
		while( inFile >> temp )
		{
			list.push_back( temp );
			++count;
		}
	}
}
You'll need to overload the >> operator of Payroll for this to work. Either that, or extract each data item into individual variables, and construct a temporary Payroll object from them. then push_back the temp object.

did you see the edits to my above post?

I don't have time tonight to get into the details of how to make a constructor that would read an entire record. But someone else should be able to help.
