c++ - What does sizeof(int) return in this case? -

- 

  # शामिल हैं & lt; stdio.h & gt; # से & lt में शामिल हैं, conio.h & gt; शून्य मुख्य () {if (sizeof (int) & gt; = - 2) printf ("true"); अन्य प्रिंटफ़ ("गलत"); }

जब मैं टर्बो सी ++ का उपयोग करते हुए कोड के इस टुकड़े को संकलित करने का प्रयास कर रहा हूं तो यह सत्य के बजाय झूठी लौट रहा है। लेकिन जब मैंने कार्यक्रम के मूल्य को प्रिंट करने की कोशिश की तो वह 2 लौट रहा है।

यह कैसे संभव हो सकता है? जबकि sizeof (int) वापस 2 और हां 2> = - 2 है।

आकार (int) प्रकार std ::

हस्ताक्षरित हस्ताक्षर के साथ हस्ताक्षर की तुलना अजीब परिणाम के कारण होता है क्योंकि हस्ताक्षरित अहस्ताक्षरित में पदोन्नत किया गया है।

आकार_t 

  यदि (static_cast और lt; int & gt; (sizeof (int)) gt2 = /)

यदि आप यदि ((int) sizeof (int) & gt; = -2) संकलित करने पर सी संकलक 

  पर काम कर रहा है उदाहरण के लिए, कुछ चेतावनी झंडे  -Wall  के साथ कोड को हस्ताक्षरित / अहस्ताक्षरित तुलना के बारे में संभवतः चेतावनी देनी चाहिए (यदि आप चेतावनियों की अनदेखी नहीं कर रहे हैं)

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
