convert to loop

[jvardam]

How do i make this so it keeps repeating unless a -1 is inputed. And when inputed it couts a statement. I have tried do while and if but it messes up on me everytime.

 #include<iostream>

using namespace std;



int main()

{

	long bin, dec = 0, rem, num, base = 1;



	cout << "Enter the binary number(1s and 0s) : ";

	cin >> num;

	bin = num;

	while (num > 0)

	{

		rem = num % 10;

		dec = dec + rem * base;

		base = base * 2;

		num = num / 10;

	}

	cout << "The decimal equivalent of " << bin << " : " << dec << endl;

	return 0;

}

how about this?

#include<iostream>
#include<cstdlib>


using namespace std;



int main()

{

	long bin, dec = 0, rem, num =1, base = 1;

    while (num != -1)
    {


	cout << "Enter the binary number(1s and 0s) : ";

	cin >> num;

	bin = num;

	while (num > 0)

	{

		rem = num % 10;

		dec = dec + rem * base;

		base = base * 2;

		num = num / 10;

	}

	cout << "The decimal equivalent of " << bin << " : " << dec << endl;
    }

	return 0;

}

it still messes up on big numbers like 10010000 and also when - 1 is inserted it needs to output a message like all set

Jvardam I am not sure i understand, Binary number 10010000 is in decimal 144
this is what your code shows, and here you have confirmation on the web

What do you want to happen when you break loop?
