A boolean is a variable type that can only be two different values True or False same as it is in most programming languages but in C# booleans are stated as: public bool var = True; or public bool var = False;

To determine the number of words, initialise a counter (0) and a bool (false). Scan the text one character at a time. If the character is a letter or a digit and the bool is false, set the bool to true and increment the counter. If the character is not a letter or digit and the bool is true, set the bool to false unless the character is a hyphen. When you're done, the counter will tell you how many words there were. To determine the number of lines, divide the string's length by the line length. If there's a remainder, round up to the next integer.
Bool Lagoon Game Reserve was created in 1967.
The question is not clear. If you mean can you write a C++ program such that the main function returns a boolean, the answer is no, you cannot. The main function must return an int to the operating system. However, the return value can be treated as boolean such that non-zero indicates true (an error has occurred) and zero indicates false (no error). Unlike C, C++ does include a primitive bool data type which can only be true or false. All the comparision operators such as ==, !=, <, <=, > and >= return bool and all the integral data types (int, char, wchar_t) can be implicitly converted to and from bool. Converting a bool to an int returns the value -1, since false is typically imlemented with all bits set while true is implemmented with all bits unset.
Python has two constant objects, True and False and a bool() function. The bool() function simply casts its argument to one of the two Boolean objects. All integral types (integers) will implicitly cast to True or False, such that the value zero is always False and non-zero is always True. Floating point types can also be implicitly cast (such that 0.0 is always False) however floating point values are approximations and should never be used implicitly. Instead, use comparison operators to perform an explicit cast: if x == 0.0: # do something All the comparison operators return True or False, as do all the logic operators (and, or and not). However, it is never necessary to compare an expression with the True object: if x == True: The above can be reduced to the more efficient: if x: Where x cannot be implicitly cast to a Boolean constant, use the bool() function to perform an explicit cast: if bool(x): If you need to reverse the logic, you might use the following: if bool (x) == False: However, it is arguably more readable to use the not logic operator instead: if not (bool (x)): You can experiment with Boolean types through the bool function: bool ('') # False bool ('a string') # True bool ([]) # False bool ([1,2,3]) # True bool (0) # False bool (1) # True bool (0.0) # False bool (42.0) # True bool (False) # False bool (True) # True Note that the last two are redundant casts.
