	while (yez=="y"||yez=="Y")
	{
		cout<<"Doy you want to exit? ";
		cin>>yez;
		return 0;
	}

That doesn't handle the Enter key like the rest of the program does. I believe changing that to getline instead of cin should fix some of your issues.

Also, all of your code after that isn't a loop, it just gives the illusion of being a loop. If you learn a little more about conditional loops, it will put you on the right track.

The code is a little messy and hard to read. Have you learned about functions yet? It really helps readability and maintainability when functions are added properly.

thankyou for the answer sir ill try the cin and get back for some more info thanks again
