ans=x*y;
while (ans==guess)
{
{ cout<<"Very Good!\n";

x = rand() %10;
y = rand() %10;
cout<<" How much is "<<x<<" times "<<y<<" ?(type 111 to END): ";

ans=x*y; }
while (ans!=guess)
{ cout<<"No, Please try again.\n";
cout<<" How much is "<<x<<" times "<<y<<" ?(type 111 to END

Answer 1

The code is not whole, so I did not test if the algorytmus is OK - and the loop would be ended alone for some number of cycles.
But you write here : "type 111 to END", so you have to check in code if the value 111 was entered:. after line cin>>guess; add next line
if (guess==111) break; //breaks loop, but program continues next command
or this
if (guess==111) return; // it leaves the function main, so program is ended
Btw not (type E to END), because int variable takes only number values.
