I assume you are running into a buffering issue, such that your program exits before your buffer flushes. When you use printf() or print() it doesn’t necessarily flush without a newline. You can use an explicit flush() or add a new-line (which will also cause a flush()) See also Buffered Streams – The Java Tutorials, Flushing Buffered Streams which says in part Some buffered … Read more
It has to do with mutual exclusion. xor is exclusive. or is inclusive. Truth Table Comparison Note: the difference in the last case. xor is only true when either $x or $y is true, but not both (as the case for or).
The equivalent is a BIT field. In SQL you use 0 and 1 to set a bit field (just as a yes/no field in Access). In Management Studio it displays as a false/true value (at least in recent versions). When accessing the database through ASP.NET it will expose the field as a boolean value.
A boolean is not an integer; 1 and 0 are not boolean values in Java. You’ll need to convert them explicitly: or serialize the ints as booleans from the start.
Really, you just compare the string to whatever you expect to accept as representing true, so you can do this: Or to checks against a whole bunch of values: Be cautious when using the following: Empty strings evaluate to False, but everything else evaluates to True. So this should not be used for any kind of parsing … Read more
I think a more canonical way to do this is via: and argparse supports this version nicely: Of course, if you really want the –arg <True|False> version, you could pass ast.literal_eval as the “type”, or a user defined function …
In the following example, I’m trying to scan the value of boolean type of variable. When I compile in GCC, I get following warning, code: My question is, Is there any format specifier of bool in C

There is no format specifier for bool types. However, since any integral type shorter than int is promoted to int when passed down to printf()‘s variadic arguments, you can use %d: But why not: or, better: or, even better: instead?
