haskell - Properly import module with some definitions only visible with qualified names -

-

मान लें कि मेरे पास एक मॉड्यूल ए नामों के साथ b , सी परिभाषित।

अब मैं किसी तरह से एक आयात करना चाहता हूं और निम्नलिखित नाम सुलभ होना चाहिए:

  • ab
  • एसी
  • c

जहां अयोग्य नाम b छिपा हुआ है।

मैंने जिस पद्धति की कोशिश की है, उसे दो तरह से दो बार आयात करना है: 

  आयात ए छुप (बी) आयात योग्य ए (बी)   
 लेकिन यह ऊपर वर्णित प्रभाव को प्राप्त करने के लिए नहीं लगता है। तो ऐसा करने का सही तरीका क्या है?   
 
 
 आपको करने में सक्षम होना चाहिए  < प्री>  आयात ए (सी) आयात योग्य ए   
 या  
  आयात ए छुप (बी) आयात योग्य ए   
 को केवल आपको  c  तक पहुंच प्रदान करनी चाहिए, फिर सब कुछ अंदर  A  योग्य वाक्यविन्यास का उपयोग करना यदि आप इसका परीक्षण जीएचसीआई में कर रहे हैं, तो याद रखें कि जीएचसीआई के पास कुछ अतिरिक्त विशेष सामान हैं जो इसे एक मॉड्यूल के अंदर पहुंच प्रदान करने के लिए अनुमति देता है जो इसे स्रोत से लोड किया गया है क्योंकि इसका प्राथमिक उपयोग अन्वेषण और डीबगिंग है।

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
