Is there a function in c that returns the index of a string in another string? -


मेरे पास 2 वर्ण एरे हैं 

  चार पृष्ठ = [4] [5] = { {'ए', 'बी', '', 'डी', 'ई'}, {'ए', '', 'सी', 'डी', 'ई'}, {'ए', 'बी' , 'सी', 'डी', 'ई'}, {'ए', 'बी', 'सी', 'डी', 'ई'}}; चार शब्द [5] = "सीडीई";   
 मैं  पेज  में शब्द "सीडीई" के सूचकांक ढूंढने की कोशिश कर रहा हूं, अर्थात् 7 और 17. क्या इस के लिए सी में कोई फ़ंक्शन है? या एक छोटा रास्ता कुछ ऐसा,  
  int indexlist [] = खोज इंडेक्स (शब्द, पृष्ठ);    
 
 
 आप निम्न प्रयास कर सकते हैं:  
  # शामिल करें & lt; stdio.h & gt; #include & lt; string.h & gt; {'ए', 'बी', '', 'डी', 'ई'}, {'ए', '', 'सी', ' डी ',' ई '}, {' ए ',' बी ',' सी ',' डी ',' ई '}, {' ए ',' बी ',' सी ',' डी ',' ई ' }}; चार शब्द [5] = "सीडीई"; // एक एकल स्ट्रिंग में सभी वर्ण डाल: चार बफ [21]; memcpy (buf, & amp; (पृष्ठ [0] [0]), 20); // और रिक्त समाप्त: buf [20] = '\ 0'; चार * पी; p = buf; जबकि ((p = strstr (p, शब्द))! = NULL {printf ("% d के ऑफसेट पर एक मैच मिला \ n", (int) (p - buf)); पी + = strlen (शब्द); }}   
 आउटपुट:  
  7 के ऑफसेट पर एक मैच मिला 17 की ऑफसेट पर एक मैच मिला

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
