If I enter blank or nothing for fill color it is not asking again to enter. Am I missing something with the code below? The radius portion works just fine.

int main$()$

$\{$

std::cout $<<"--$ Lab $2-$ Class Creation $"<<$ std::endl;

int radius;

Circle circle;

do $\{$

do $\{$

std::cout $<<$ "Radius of Circle as a positive number $(-1$ to exit$)$: $"$;

std::cin $>>$ radius;

if $($radius $==-1)\{$

return $0$;

$\}$

circle.setRadius$($radius$)$;

$\}$ while $($circle$.$getRadius$()!=$ radius$)$; $//$ Keep asking until valid radius is entered

std::string color;

do $\{$

std::cout $<<$ "Fill Color of Circle $($blank not allowed$)$: $"$;

std::cin $>>$ color;

circle.setColorFill$($color$)$;

$\}$ while $($circle$.$getColorFill$()!=$ color$)$; $//$ Keep asking until valid color is entered

displayCircleInfo$($circle$)$;

$//$ Pause for the user to read the displayed information

system$("$pause$")$;

$\}$ while $($true$)$;

return $0$;

$\}$
