Remenber where Dominick said:

"if" "(" condition ")" statement1 "else" statement2

an if-else block can look like any of:

if(...)
  statement;
else
  statement;

or

if(...) statement; else statement;

or

if(...) {
  statement1;
  statement2;
}
else {
  statement3;
  statement4;
}

or 

if(...) {
  statement1;
  statement2;
}
else
  statement3;

Your:

> else //(integer1 % 2 !=0)
> std::cout << "Your number is odd." << std::endl;

is the equivalent of:

else
 std::cout << ......;

so it has become a proper else block.  The 'if' section (the "is integer
even" test) was already properly constructed.
