With C, you have limited options. You can do the typecasting that you don’t like when you call the function: void MyFunction(unsigned char* Var); int main(void) { unsigned char Var1 = 5U; signed char Var2 = 5; MyFunction(&Var1); MyFunction((unsigned char *)&Var2); } you can use void * and typecast in the function itself and just … Read more

Java 8’s enhancements to the Comparator interface make it a lot more elegant: public static final Comparator<Student> BY_NAME = Comparator.comparing(Student::getName); public static final Comparator<Student> BY_Gpa = Comparator.comparingInt(Student::getGpa); solved Comparator in Java [closed]
Here’s a simple example using a timer. The screen is filled with a color that changes every 0.4 seconds. import pygame import itertools CUSTOM_TIMER_EVENT = pygame.USEREVENT + 1 my_colors = [“red”, “orange”, “yellow”, “green”, “blue”, “purple”] # create an iterator that will repeat these colours forever color_cycler = itertools.cycle([pygame.color.Color(c) for c in my_colors]) pygame.init() pygame.font.init() … Read more
Is this what you want?, try adding the below lines of code to your code: plt.xticks(rotation=90) plt.gca().margins(x=0) plt.gcf().canvas.draw() tl = plt.gca().get_xticklabels() maxsize = max([t.get_window_extent().width for t in tl]) m = 0.2 # inch margin s = maxsize/plt.gcf().dpi*150+2*m margin = m/plt.gcf().get_size_inches()[0] plt.gcf().subplots_adjust(left=margin, right=1.-margin) plt.gcf().set_size_inches(s, plt.gcf().get_size_inches()[1]) 4 solved Matplotlib spacing in xaxis
The problem was that you initialized some values that caused errors during the first iteration when you check for the smallest number. I added the following condition that will set the smallest number to the current number, but only during the first iteration. if (count2 == 1 || num < smalled ) { smalled = … Read more
I have adapted the java example from the wikipedia article: In this example we have different roles, each having a fixed purchasing limit and a successor. Every time a user in a role receives a purchase request that exceeds his or her limit, the request is passed to his or her successor. A builder allow … Read more
10000 on the real time clock is always going to be in the past, so your alarm fires immediately. You want System.currentTimeMillis() + 10000 as the second argument in the setRepeating() call. I would point out that setRepeating() is inexact as of KitKat, so the actual time the alarm fires may be off. If it … Read more
for 803->800 use round(803,-1), for 900.5->900 use floor(900.5). for more examples you better take a look at http://php.net/manual/en/function.round.php 2 solved How can I round up values in PHP [duplicate]
