This program reads a file called golfers.txt,
and it calculates the total and average for each golfer.
output is written to the screen.

At line 95, you declare two variables, hours and rate, but you don't initialise them. You then immediately try to use their values, despite the fact that you haven't given them any values.

Doesn't your compiler warn you about using uninitialised values?
GokuK97 (73)
it does and it has to read data from txt file above
that my my whole to read data from txt and store it in array and how to read data, for example if hours <= 40, so will it know how many hours are there

Try fixing the issue MikeyBoy mentioned and see what happens next.

I don't understand what you're trying to say here.

But your regular function function isn't working, for the reasons I've explained - it's trying to use the values of hours and rate, but you haven't given them any values.

Edit: You should pay attention to the compiler warnings. They usually tell you useful things.

1. Move the file pointer to the next line of your file before starting the loop. One way of doing it can be
char buff[255] = {0}; inputFile.getline(buff, 255);
2. Read the input in a correct sequence as stored in your input file. example:
while (inputFile >> hours) // there is a line of data to read
{
inputFile >> rate;
inputFile >> employee;
inputFile >> firstname;
inputFile >> lastname;
