इस सवाल का पहले से ही एक उत्तर है: < 14 जवाब

सी घोषणा के बारे में शुरुआती प्रश्न: / p>

  • एक। सी फ़ाइल में, किसी अन्य। सी फाइल में परिभाषित चर का कैसे उपयोग करें?

फ़ाइल ए में: 

  int myGlobal = 0;

में fileA.h 

  extern int myGlobal;

में fileB.c: 

  #include "fileA.h" myGlobal = 1;

तो यह कैसे काम करता है:

  • fileA.c में चर रहता है
  • fileA.h दुनिया को बताता है कि यह मौजूद है, और इसका क्या प्रकार है ( int )
  • fileB.c में fileA.h भी शामिल है, ताकि कंपाइलर myBlobal के बारे में जानता है इससे पहले कि fileB.c इसका उपयोग करने की कोशिश करता है।

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created.
