How can I use struct defined in one class in a different class in C++? -


मेरे पास एक वर्ग में यह संरचना है, Class1 । 

 < कोड> स्थिर संरचना गणना {int member1; इंट सदस्य 2; Int सदस्य 3; } Count1, count2, count3;   
 में  Class1 , मैं  गिनती  चर के सभी तीनों में वृद्धि कर रहा हूँ और इसे फिर से  Class2  एक अलग फ़ाइल में मैं यह कैसे कर सकता हूँ? क्या मुझे एक शीर्ष लेख फ़ाइल में  Class1  को शामिल करने की आवश्यकता है?

स्थिर चर गुंजाइश सीमित है लेकिन अगर आप कक्षा 1 परिभाषा के अंदर गिनती संरचना को घोषित करते हैं, तो जीवनकाल पूरे कार्यक्रम के माध्यम से है, फिर भी आप कक्षा 2 में इस स्थिर गिनती ऑब्जेक्ट का उपयोग नहीं कर सकते हैं, भले ही आप उस फ़ाइल को शामिल करें, जहां कक्षा 2 को परिभाषित किया गया है। आपको फाइल में गिनती संरचना को वैश्विक बनाना है और फिर इसमें फ़ाइल को 2 कक्षा में प्रवेश करने के लिए शामिल कर सकते हैं

Django Celery - running scheduled tasks -

After several hours on this without the result, I really need help I'm able to run Django-Celery with my Django app and I scheduled tasks on it: dragon manage.py celeryd -E -B -l INFO Now it is time to produce and here it is that my pain begins. I have configured the cellarid as the daemon, it works, but scheduled tasks will not work. So I added -b to CELERYD_OPTS . My tasks are now run as scheduled, but these are the boring lines on my logs: [2014-02-17 22: 37: 30,738: debuts / main process] Beat: 5.00 Waking in seconds I just want to delete that line from my logs! I did not even understand what it meant. So I had configured the Selerbeat daemon, thinking it would be a cleaner and suggest a solution to the production environment. Unfortunately, when I stop the celerybeat daemon, it creates a log and a PID file but scheduled tasks do not work. Info / main process] green: ... [2014-02-17 19: 15: 41,921: information / main process] write entries. .. [...
