primes - Project Euler #10, java -


संभव डुप्लिकेट:

इसलिए, मैं जावा में हल करने का प्रयास कर रहा हूं, और मुझे सही जवाब नहीं मिल रहा है। यहां मेरा कोड है: 

  सार्वजनिक वर्ग समस्या 10 {सार्वजनिक स्थिर शून्य मुख्य (स्ट्रिंग [] args) {long sum = 0; के लिए (इंट I = 3; i & lt; 2000000; i + = 2) {if (प्राइम (आई)) {sum + = i; }} System.out.println (sum); } सार्वजनिक स्थिर बूलियन isPrime (int n) {बूलियन प्राइम = सच; यदि (n & lt; 2) वापसी झूठी; यदि (n == 2) सत्य वापस; यदि (n% 2 == 0) वापसी झूठी; के लिए (इंट आई = 3; आई & lt; = मठ.sqrt (n); i + = 2) {if (n% i == 0) {prime = false; टूटना; }} वापसी प्रधानमंत्री;  
 (कोई भी विचार)  
 (इसके अलावा, मैं अपनी पद्धति को जानता हूं)  
 Primes ढूँढने के लिए बहुत ही अक्षम है।)   
 
 
  के लिए (int i = 3; i & lt; 2000000 ; I + = 2)  
 
 2 प्रधान है।

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
