I am about to rip my hair out with the results im getting from this simple file I/O program

ian sobo (5)
Hello everyone. I am incredibly, incredibly frustrated and confused. ALL i am trying to do is read in a list of names from a master.lst, which contains 3 lines only, 3 names.

Then, read in data from a .dat file, and put the data into variables.

When i run this program ALL I GET is a random-ass float value in the middle of the .dat file, from nowhere. all the previous data that was in there was erased. Please, for the love of god, help me.

OKAY, so i figured out if i comment out the open function for the OUTPUT file, it works, (so far). does anyone want to tell me WHY this happens?


Thanks.


EDIT: ALSO, i am having trouble reading another string in from the data file. It reads in the first one perfectly fine, but the last one, jobDescrip, simply does not do anything. Any help?

Okay, i feel like a doofus lol. After my initial freaking-out frustration (somewhat reminiscent of Bryan Cranston's freakouts), I've figured out a lot of things. Let me finish up my code, and i will post my updated source here in a second.


oh, and thanks for responding!

}


now my ONLY PROBLEM here is that it simply does not read in jobDescrip from the input file!

inFile >> payRate; // using >> before getline() is terrible
cout << "Contents of payRate " << payRate << endl;

// to stop conflicts w/ >> and getline(), add this line :
inFile.ignore();   

getline (inFile, jobDescrip);
cout << "Contents of jobDescrip " << jobDescrip << endl;


add that <object_name>.ignore() for every occurance in your code in which you're going to use getline() after >> operator
