fstream isnt getting the data right

May 8th, 2005

I'm running into to this problem where the fstream is suppose to read data off a file to store in arrays. I cant continue with my project until the program reads it right. It is skipping some of the datas. Can I get a little help? Thanks in advance

Which parts of the data are being skipped? Help us to help you by narrowing down the problem as much as possible. Otherwise we'll just ignore you.

I'm here to prove you wrong.

Re: fstream isnt getting the data right

May 9th, 2005

I'm sorry for being dimwitted. Ok the first problem is that when I go in to my menu to choose read option it would skip the 0's in the first column for example
000001 Moshiur Ahmed I CA 90805 40 12.50
fstream would get only
1 Moshiur Ahmed I CA 90805 40 12.50.

My second problem is that fstream would only read and get up to or so
1 Moshiur Ahmed I CA 90805 40 12.50
2 Tasmia Amaat J CA 90706 35 25.60
3 Victor Barboza K CA 90706 42 30.00
4 Carlos Detorres I CA 90804 50 20.45
5 Tyree Ek O CA 90755 60 15.60
6 Amine El-Maziati M CA 90815 20 9.75
7 Loubna El-Maziati M CA 90815 25 10.50
8 Theresa Eyssallenne L CA 90715 40 20.00
9 Craig Griffith I CA 90804 40 45.00
10 Rodney Hallett H CA 90808 43 25.25
11 Andrew Hegstrom P CA 90808 45 13.50
12 Corey James D CA 90815 40 20.00

After this it would replace everything with 0's. Is it becasue there is something wrong with how I set it up or maybe the arrays are wrong.

Oh if you would like to run my program the ID code that it will asks for is "lbcc"

Well that's easy. Leading zeros are meaningless on an integer, so they're ignored. If you want the whole string, read it as a string instead of an integer.

>After this it would replace everything with 0's.
Well, your array is of size 100 and there are only 30 records in the file you gave us...

I'm here to prove you wrong.

Yeah I know there is only 30 record but Its only reading 13 records. At first it was at a array of 30 but it would read up to 13 records and still had 0's so change it to 100 but still the samething

Hi everyone,
I ran into another problem. Im trying to sort the employees records by using the bubble sort with arrays and I just got the names arrays down but how would I get the rest of the information of that employees to go next to the names.

void sortLastname(int a)
{
	string temp = string();
	char pick = char();
 
	for(int i=0; i<30; i++) 
	{
		for (int j=0; j<30-i; j++)
		{
			if (lname[j] > lname[j+1])	// compare the two neighbors 
			{  
				temp = lname[j];         
				lname[j] = lname[j+1];	// swap lname[j] and lname[j+1]      
				lname[j+1] = temp;
			}	
		}
		cout << temp <<endl;
 
		//cout << setw(5) << left <<  ID[i] << setw(10) << left << fname[i] << setw(12) << lname[i] << setw(2) << middlei[i] << setw(7) << state[i] << setw(5) << right << zip[i] << setw(6) << right << hrWork[i] << setw(8) << right << ratePhour[i]  << endl;
	}
void sortLastname(int a)
{
	string temp = string();
	char pick = char();

	for(int i=0; i<30; i++) 
	{
		for (int j=0; j<30-i; j++)
		{
			if (lname[j] > lname[j+1])	// compare the two neighbors 
			{  
				temp = lname[j];         
				lname[j] = lname[j+1];	// swap lname[j] and lname[j+1]      
				lname[j+1] = temp;
			}	
		}
		cout << temp <<endl;
		
		//cout << setw(5) << left <<  ID[i] << setw(10) << left << fname[i] << setw(12) << lname[i] << setw(2) << middlei[i] << setw(7) << state[i] << setw(5) << right << zip[i] << setw(6) << right << hrWork[i] << setw(8) << right << ratePhour[i]  << endl;
	}

Would I have to use another bubble sort in the bubble sort? Why is it that I cant seem to edit my first post. I like to paste my updated code.
