I’m new to learning c++, and I’m really enjoying following this tutorial.

My question is this:
When i run the program it correctly keeps asking for a number between 1 and 9 as long as i input a number when prompted. However if I input a letter (Tried it to see what would happen incase of a misstype) it seems to go into an endless loop. Is it supposed to do that (with the code written) or is there another way to avoid this problem I should implement?

#include "stdafx.h"
#include <iostream>
using namespace std;

int main()
{
	int x;
	do
	{
		cout << "Please input a number between 1 and 9: ";
		cin >> x;
	}	while (x < 1 || x > 9);

	int anArray[9] = {4, 6, 7, 3, 8, 2, 1, 9, 5};
	for (int iii = 0; iii < 9; iii++)
		cout << anArray[iii] << " ";

	cout << endl;

	for (int jjj = 0; jjj < 9; jjj++)
	{
		if (anArray[jjj] == x)
		{
			cout << "The number you entered (" << x << ") has index number: " << jjj << endl;
			break;
		}
	}

	return 0;
}

#include "stdafx.h"
#include <iostream>

int main()
{
	using namespace std;
	int nInputNumber;
	do
	{
		cout << "Please enter a number between 1 and 9: ";
		cin >> nInputNumber;
	}while((nInputNumber < 0) || (nInputNumber >= 9));

	const int nArrayElements = 9;
	int anArray[nArrayElements] = { 4, 6, 7, 3, 8, 2, 1, 9, 5 };
	cout <<"The array contains the following elements: ";
	int nInputElement = -1;  // This will hold the place of the input number.
	for(int iii = 0; iii < 9; iii++)
	{
		cout << anArray[iii] << " ";
		if(anArray[iii] == nInputNumber)
			nInputElement = iii+1;
	}
	cout << endl;
	cout << "Your number was element number " << nInputElement << "." << endl;
	return 0;
}

} while ( h <= 1 || h >= 9);

I’m getting a “syntax error : ‘<’” when I try to compile; it’s pointing to this line:

} while (h = <1

My code looks the same as yours!!!! This is driving me nuts! What have I done wrong?

and this is just 4 students!

should be

and this is just 5 students… *sigh* I hate when people do that to me.

Also I would like to thank you very very very much for all the work you put into this.
I’m aspiring to be a programmer for pixar (or square-enix… not a fan of the new disney owners).
I’m working on a game right now and when im done i just have to let all who plays it know about this site, its amazing. THX YOU!
