I am trying to write a program to input two integers so that several sets of data
can be processed...having trouble nesting within statements.

#include <iostream>
using namespace std;
int main()
{
		//variable declarations
	int a = 0;
	int b = 0;
	int	set_no = 0;

		//prompt user for integers
	cout << "\nEnter Set number ==>";
	cin  >> set_no; 
	cout << "Please enter value for Integer A and press the Enter key ;";
	cin >> a;
	cout << "Please enter value for Integer B and press the Enter key ;";
	cin >> b;

	while (!(set_no == -999))
	{
			//decide whether Integer A is larger than Integer B
		if (a > B)/>
		{	cout << "Integer A ";
			cout <<a;
			cout <<" is larger than Integer B ";
			cout <<b;
			cout <<"\n";
		}
		else
		{	cout << "Integer A ";
			cout <<a;
			cout <<" is not larger than Integer B ";
			cout <<b;
			cout <<"\n";

		}//end if

	
		cout << "\nEnter Set number ==>";
		cin  >> set_no; 
		cout << "Please enter value for Integer A and press the Enter key ;";
		cin >> a;
		cout << "Please enter value for Integer B and press the Enter key ;";
		cin >> b;

	}//end while


	cout << "\n   End of Program\n";


				//Add lines for Visual Studio 2010
	int xx;
	cout << "\nPress any key to continue, then hit the Enter key!";
	cin >> xx;

	return 0;

}//end of program

look here


if (a >


but you have declared it as b in the start

b is not the same as B

sorry smiley came in there and cannot stop it

I meant to say look here

on line 7 you declare b = 0 ;

but then on line 21 you capitalise the b

[sk1v3r]

Actally, I believe that that is a problem with the website, b's get capitalized on occasion.

Also, you say that you are having problems, but could you name them specifically please

Also, some nice shortcuts that can make your code simpler

!(a == B)/>
// is the same as
(a != B)/>

// and another good thing
cout << "one " << one << endl;
// is the same as
cout << "one ";
cout << one;
cout << endl;
// the << operator can be used like this to save lines.

Thanks but the problem is with the while and if/else loops....trying to get a prompt to handle multiple data sets...

[jimblumberg]

I would suggest that you look into using arrays to hold your "sets".
