I have the following method :
char getChar(int I)
{
if (I<65+26) return (char)(I);
switch (I)
{
case 91 : return '?';break;
case 92 : return '#';break;
default : return ' ';
}
}
Why does it get "unreachable statement" error ?
Because you can't break
after you have already return
ed. return
means "exit the method". break
means "exit the block".
So if you have:
return '?'; break;
then the break
can never be reached.
You probably don't need a break
statement after a return
, since control has already left the structure (even the entire method) by way of the return
:
switch (I)
{
case 91 : return '?';
case 92 : return '#';
default : return ' ';
}
Anything after a return
would never be reached.
