Using code tags will make it easier to read, thx.

Don't waste any time responding to this rubbish. It's just a troll/plagiarist at work and this one gets posted here from time to time.

https://projectorg.files.wordpress.com/2012/04/shubhangi-ams1.doc

PS The indicator with this type of moronic OP is a similar request, a long piece of untagged and outdated code from a low score poster - often post count 1 or 2 only. A Google search on these is invaluable if you are tempted to good-faith respond.

Apologies. I Was Asked To Make A DB As A Project, But Due To Time Constraints, I Was Forced To Get One Online. Even So, I Haven't Completely Copied The Code. I Added A Few Minor Changes But They Refused To Work, Hence I Approached This Helpful Forum. I Had No Intention Of 'Trolling' Or 'Plagiarism'.

Try putting this after your include statements.
using namespace std;

I'm thinking you might want to open the file in binary mode, you might also want to set your out-files to append mode since they otherwise will overwrite previous entries.

Those sleep commands really upset me, what is the point of decreasing the efficiency of your program? It just serves to make the user think your program is heavy and bogged down when you could be impressing them with its speed and usability.

But your biggest problem is copyright law. Don't ever use copy/paste, especially if you are in a corporate setting. If you're a student then you should learn pretty quickly that your teacher is much better at searching google than you are. You can quickly get expelled from a college for this level of plagiarism so don't just try to brush it off as no-big-deal.

google search the next line;

cout<<endl<<endl; cout<<" "<<"SEARCH IS ON"<<endl; cout<<" "<<"============"<<endl<<endl; cout<<" "<<"PLEASE ENTER YOUR NAME ::"<<endl; cout<<" ";gets

And suddenly you are no longer a college student, is it worth it?

[SamuelAdams]

I agree with newbieg, only cut and past your own code, and then don't do it when your sleepy. I learned that the hard way. You can cut and paste your bad code all over the place quicker than thought.

You can read someone's code and use the concepts you learn but make your own. Plus then you'll understand it :P

Hmm, the funny thing is that the original pdf that this was taken from no longer shows up when you search the line that I give above.

Probably was illegally posted to begin with and someone took it down...

Anyway, the teacher also has access to databases like http://smallseotools.com/plagiarism-checker/, or moss, and who knows what they're actually using or if they are even using them at all, but it's still not worth the risk.
