weird input skipping

[chickens7]

Hey all!, I've made a class with will add fractions, but when I try to loop it in the driver code as shown below, it works great on the first iteration, but after that, it skips over the first input and all I can enter is the second fraction. for example on the second go-around, it will display
enter a fraction
enter another.
I would link the rest of the code, but its huge and annoying, and I believe (hope anyway) that the problem is here.

  #include "rational.h"

int main()
{
	char ans;
	int selection;
	rational *fraction1, *fraction2;

	
	do
		{

			fraction1 = new rational;
		    fraction2 = new rational;
			cout << "enter a fraction\n";
			cin >> *fraction1;
			cout << "enter another\n";
			cin >> *fraction2;
			cout << *fraction1 + *fraction2;
			cout << "go again y/n\n";
			cin >> ans;
			delete fraction1, fraction2;


	} while (ans == 'y');
	

}

lol my bad fixed it already, cin.ignore() so fail

I'm not sure the delete function behaves in the way you have used it above.

Example:

To fix the issue, with the code, after the last call to cin, put this line:

#include <iostream>
#include <limits>
...
cin.ignore(numeric_limits<streamsize>::max(), '\n');

...And ninja'd by OP

That works like a champ too, thanks!
