You’re missing a return
statement.
When the compiler looks at your code, it’s sees a third path (the else
you didn’t code for) that could occur but doesn’t return a value. Hence not all code paths return a value
.
For my suggested fix, I put a return
after your loop ends. The other obvious spot – adding an else
that had a return
value to the if-else-if
– would break the for
loop.
public static bool isTwenty(int num)
{
for(int j = 1; j <= 20; j++)
{
if(num % j != 0)
{
return false;
}
else if(num % j == 0 && num == 20)
{
return true;
}
}
return false; //This is your missing statement
}
