The first method you are calling is Read which returns one character. But it blocks until you hit the Enter key. From MSDN: The Read method blocks its return while you type input characters; it terminates when you press the Enter key. Then you call ReadLine which returns a line. When you hit the Enter … Read more
Standard ‘learning the language’ warning: This isn’t C++ you’re writing, it’s C++/CLI. C++/CLI is a language from Microsoft intended to allow C# or other .Net languages to interface with unmanaged C++. In that scenario, C++/CLI can provide the translation between the two. If you’re still learning C++, please do not start with C++/CLI. In order … Read more
you can do the following: explanation for the code: Square is formed of 2 equal sides, so in order to draw the square using *, you will think of it like a matrix you need a loop to draw the rows and another loop to draw the columns, and both loop has upper limit which … Read more
In Java 8 streams, you can generate a stream of integers between two numbers using: IntStream.range(lower, upper)… If you want them to be randomised, then you can use: Random random = new Random(); random.ints(count, lower, upper)… You can then use methods such as forEach, reduce or collect to do something with the stream. So, for … Read more
You have to coding something by yourself. >>> [sum(x) for x in a] [5, 7, 5]
The problem is here: (bool) (flag2 ? 1 : 0). You’re trying to convert an integer to a boolean using an explicit cast. Use Convert.ToBoolean instead: Convert.ToBoolean(flag2 ? 1 : 0). BTW, it seems like it’s so useless: why do you want to convert 1 to true and 0 to false if flag2 is already … Read more
You ask for a number, but you are trying to compare it to non-numeric data. Forget language semantics, how do you expect to compare a number to text? What does it mean to ask if a number like 3 is equal to “higher”? The answer is that it is nonsensical; this is one reason why … Read more
If you want to know if the result of dividing a $dividend by a $divisor is going to be a whole number or a number with a fractional portion, you can test that condition first: if (my $remainder = $dividend % $divisor) { print “$dividend cannot be divided evenly by $divisor.”, ” There is a … Read more
You can rewrite the function like below: def concatenate_list_data(list): result=”” for element in list: result += str(element) return result my_result = concatenate_list_data([1, 5, 12, 2]) # leads to 15122 Another approach to the same can be using a list comprehension: to_join = [1, 5, 12, 2] output=””.join([str(i) for i in to_join])
