Hi!

I'm taking a class in c++ and am having to write a pretty big program
that involves vectors, push-backs, etc.

I'm trying to do this thing one step at a time to make sure everything
works right.

The problem I'm having is that when I go to run the program, all I see
is "Press any key to continue", I don't see my menu. It builds okay
without any errors.

Can someone take a look and see what might be causing it not to show up
on the screen.

Thanks!

/* Program Description: Program will keep track of a hardware store's
inventory. The store sells various item.s For each item in the store,
the following information is kept- item ID, item name, number of pieces
ordered, number of pieces currently in the store, number of pieces sold,
manufacturer's price for the item, and the store's selling price. At the
end of each week, the store manager would like to see a report that
shows the item ID, item name, pieces ordered, pieces in the store,
pieces sold, manufacturers price and the selling price.*/

#include <iostream>
#include <iomanip>

using namespace std;

// function prototypes

void printMenu();

int main()
{
ifstream inFile; // input stream variable

// variable declaration


inFile.open ("e:\\cosc1437\\p2data.text"); // open data file
if (!infile)
{
cout << "Input file (p2data.text) does not exist." << endl;
return 1;
}

printMenu();

inFile.close();

return 0;
}

void printMenu()
{
cout << " ---------------------Menu--------------------" << endl <<

Good plan.

I take it that most of these headers are for use later on in the program?

Personal preference, have main() at the end - it avoids prototyping.

On my machine, it prints the menu (I've removed the infile bit for obviously
reasons).

What it could be is that you're running the program from within VisualStudio
(assuming that's what it is you're using). That has a very nasty habit of
not showing what is going on. Try opening a command window and running the
program from within there.

Almost works for me. Had to add one << as noted and take out the file
stuff, since I don't have the file.
That's on DevC.

Got that fixed!

Hi!

Yes, the headers are for later use in the program. As for main, that's
the only way I've learned where to put it.

I've not used VS very much and don't know all of it's finer workings!
How do I open the command window?

Thanks!
