c++ - I get 20 errors in the algorithm file when trying to sort a struct vector. I don't know what is wrong? -

-

यह मेरा कोड है 

  #include & lt; stdio.h & gt; # शामिल करें & lt; cstdio & gt; # शामिल करें & lt; math.h & gt; # शामिल करें & lt; एल्गोरिथम & gt; # शामिल करें & lt; सेट & gt; # शामिल करें & lt; struct.h & gt; # शामिल करें & lt; vector & gt; #include & lt; कार्यात्मक & gt; नेमस्पेस एसटीडी का उपयोग करना; संरचना अंक {int x, y; }; बूल ऑपरेटर & lt; (कॉन्स्ट पॉइंट्स एंड पी 1, कॉन्स्ट पॉइंट्स एंड पी 2) {रिटर्न पी 1 एक्स। & Lt; p2.x; }; वेक्टर के & lt; अंक & gt; एक (1000000); Int i, n, निकटतम; Int main () {scanf ("% d \ n", & amp; n); (I = 0; i & lt; n-1; i ++) के लिए {scanf ("% d% d \ n", & amp; एक [i] .x, और [i] .y); } सॉर्ट (0, एन -1, ए); वापसी 0; }

त्रुटियों जो मुझे अधिकतर राज्य मिलती हैं "संकेतक सूचक सूचकांक ('int' अमान्य) की आवश्यकता होती है। क्या गलत हो सकता है? मैं वेक्टर में स्ट्रेंक्ट को सॉर्ट करने की कोशिश कर रहा हूं। प्रयुक्त ओवरलोड।

ऐसा नहीं है कि आप std :: sort का उपयोग कैसे करते हैं! प्रतिस्थापित करें: 

  सॉर्ट करें (0, एन-1, ए);

के साथ: 

  sort (a। शुरू (), a.end ());

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
