C++ help

[KeR]

this program needs to save a company's two payroll codes and correspongind salaries in a sequential access file.....

and this is what I have so far:

the only problem is it does not stop when I enter the 3rd salary

Code Salary

A 27200

B 15000

C 23000

#include

#include

#include

using namespace std;

int main()

{

ofstream outFile;

outFile.open("T13ConE09.dats::app);

if (outFile.is_open())

{

string code = "";

int sales = 0;

int counter = 0;

cout << "Code (X to stop): ";

getline(cin, code);

while (counter < 3 )

{

cout << "sales: ";

cin >> sales;

cin.ignore();

counter = counter + 1;

outFile << code << '#' << sales << endl;

cout << "Code: ";

getline(cin, code);

}

outFile.close();

}

else

cout << "File could not be opened. " << endl;

return 0;

}

Well, I don't know a lick of c++, but i managed to get it to work like this:

<pre>#include <iostream>

#include <fstream>

#include <string>

using namespace std;



int main()

{





  ofstream outFile;

  outFile.open("T13ConE09.dats::app);



  if (outFile.is_open())

    {

      string code = "";

      int sales = 0;

      int counter = 0;

      cout << "Code (X to stop): ";

      getline(cin, code);

      while (counter < 3 )

	{

   if(counter)

     {

       cout << "Code: ";

       getline(cin, code);

     }



   cout << "sales: ";

   cin >> sales;

   cin.ignore();

   counter = counter + 1;

   outFile << code << '#' << sales << endl;

	}

      outFile.close();

    }

  else

    cout << "File could not be opened. " << endl;

  return 0;



}

</pre>

EDIT: File didn't save properly, fixed.

thanx bro now the only problem I have is when I enter the Code I have to hit Enter twice.....is there a way so that I can only hit Enter once?

[Hatter]

it doesn't do that on my system (Linux, g++) so i'm not sure. I did change my code up above though as the file wasn't saving right. Try the new code and see if your problem was somehow related.

here is the problem:

I'm assuming it has to do with your use of getline() instead of cin but I cannot reproduce the problem so i can't test this. Try getting the user input for 'code' with cin.

There are only 2 lines to replace.

[KeR]

which ones....

lol as you can see I am a beginner at this

[Hatter]

I've never coded C++ in my life ;)

I just noticed that code is a string, so I dont know if cin can be used for strings. If it can, replace the getline() lines with cin >> code;

Don't quote me on any of this ;)

[Hatter]

well, judging from trial and error, cin doesn't support string.

So i guess your stuck ;)

thanx it's working now:D

try putting a space in there ;)

As long as you only need chars (you should be using a char variable, no?) then it should work fine.

that worked even better.....

cin supports *char and string. Why would a standard library not be able to support another???

As I mentioned above, i've never coded C++ before nor read about its libraries. I was unsure as to whether cin was similar to getchar() in C or whether it was just antoher stdin function.
