stuck on loop

[dbrank28]

My assignment has me making a wage calculator. It requires me to have an input and output file. Then input file follows as such....

1
10
39
0
0
1
15
41
2
1
1
10
49
2
1
1
10
51
2
1
0

the zero at the end signifies that the loop will stop. The inputted numbers go into variables in this order... cont(continue loop), rate , hours, dependents, fulltime. They then repeat for the next employee. The loop isnt outputting each employee, only the last employee
1, 10, 51, 2 ,1 . i have tried several different kinds of loops and parameters but still cant figure it out. any help would be great. thank you

anyone?

this code

        ofstream out_stream;

        out_stream.open("outfile.dat");
        if(!out_stream)
        {
            cout << "outfile.dat failed!" << endl;
            return 0;
        }

should be at the top of main. Currently it is within your main loop. When you open a file for output if the file already exists the data is erased. So every time you out_stream.open("outfile.dat"); you erase any previous employee data

Ah thank you. Had a couple other problems as well. Thanks for the help
