iphone - Swift Remove a given value from an array -

-

मेरे पास एक सरल सरणी है 

  var चश्मा: [स्ट्रिंग] = [बटन 1, बटन (बटन 2, बटन 3, बटन 4)

कैसे मैं अपने गुम में एक निश्चित मान (प्रकार बटन 3) पा सकता है और इसलिए रद्द कर सकता हूँ?

आप अनुक्रमणिका को पुनः प्राप्त करने के लिए find () वैश्विक फ़ंक्शन का उपयोग कर सकते हैं: 

  var ऐनक: [स्ट्रिंग ] = ["बटन 1", "बटन 2", "बटन 3", "बटन 4"] सूचकांक = खोजने दें (चश्मा, "बटन 3")

और फिर, एक बार सत्यापित हुआ कि तत्व मौजूद है ( ढूंढें एक विकल्प देता है), इसे हटा दें: 

  यदि अनुक्रमणिका = अनुक्रमणिका {specs.removeAtIndex (index)}

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...
