"return true" returns true, "return false" returns false.

For example:

bool IsBig(int number)
{
    if(number > 1000000)
        return true;
    else
        return false;
}

True and False are boolean type value on the other hand 1,2 3 are integer value and so on..

suppose you have a form and an input Box fo age.

You want to show a message "your age is under 18" or "your age is above 18" then what you do?

   you check some condition, if condition meets then it returns true else false.

 

// this method returns true or false
bool isAgeGrater18(int age)
{
 if(age >18) //when condition meets then returns true
{
  return true;
}
else
{
 return false;
}

}

 hope you are clear.

There is nothing much special in boolan values (true, false). They represent two states, its line 0 and 1 (zero, and one). They come right, when you need to check if something is ok or not.
