यह क्यों सही है? 

  char c1 = 125;   
 और यह क्यों गलत है?  
  चार सी 2 = सी 1 + 1;   
 ऊपर दिए गए कोड का सही तरीका होना चाहिए:  
  चार सी 2 = (चार) (सी 1 + 1);   
 मैं उलझन में हूँ बहुत बहुत धन्यवाद!   
 
 
 यह गलत है क्योंकि  char   पूर्णांक ।  1  में  c1  को  c1  को  int  में जोड़ा जाता है। जब आप इसे  char  java शिकायत में वापस डालते हैं, क्योंकि यह वादा नहीं कर सकता कि  int  एक  char   में फिट होगा > 
 -एडिट -  
  char c = 123  के मामले में  123  भाग ज्ञात है, इसलिए जावा वास्तव में यह वादा कर सकता है कि यह हमेशा एक  char  में फ़िट होता है यह भी काम करेगा:  
  अंतिम चार c0 = 123; चार सी 1 = सी 0 + 1;   
 और यह:  
  अंतिम अंत i0 = 123; Char c1 = i0 + 1;

sql - Postgresql record to array -

-
I need to change back into an array to change lines from the array and filter the records. I am using info_schema._pg_expandarray in a SELECT query to get a line copy value in the array. Looking at the following array: "four" [] {i, i, o, t, b} _pg_expandarray leaves 5 rows with 1 row type record: records (I, 1) (i, 2) (o, 3) (t, 4) I have to filter this result set 't' to exclude record records. How can I do this? Should I convert back to the array? What is a way to filter the array directly? Thanks in advance. If your purpose is to create one set of the above rows, but remove the 't' in the line So, this is the trick: test => Information (i), 'o', 't', 'b' i. N --- --- --- i | 1 mother 2 o | 3b 5 (4 lines) As a side, unless you specifically want to return the index as a second column, then I unnest () information_schema._pg_expandarray () , which does not appear in the document and is probably...

c++ - Cmake produces file extensions in static library archives -

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
