Not sure about efficiencies, but the purpose of an int is to store an integer and the purpose of a bool is to store a boolean value true or false.

Using a bool IMO reflects its use much better than using an int. Programmers would often typedef int Bool in order to make it clear that they were using a boolean. Sometimes the answer is just 'taste'. I bet if you rewrite your same assignment right now this moment there will be several things different such as function parameter order and their names. Why didn't you write it the same parameter order or same name?

A variable you set to 0 or 1 could be a counter; a variable you set to true or false is clearly a flag. Bools prevent abuse of a variable for other uses. An integer can be set to values other than 0 or 1 to create additional states your code may not be aware of. You could use any method you like to store the value including a string with the value "yes" or "no", but you should choose the one that makes MOST sense.

Every item about dengue would be returned, as would those that discuss both of the other two. Report a problem. Subjects: Help Topics.
