default is used with (switch statement) to handle what'll happen if non of the defined cases happened.
ex:
int x=4;
switch(x)
{
case 1: cout<<"1"; break;
case 2: cout<<"2"; break;
case 3: cout<<"3"; break;
default : cout<<"It's not 1 or 2 or 3 ..! ";
}
in that case .. we'll see (It's not 1 or 2 or 3 ..!)
