How to declare a C++ function for Arduino code? -


I got the following Arduino code to get the text from Bluetooth and bring it back to an LCD display.

When enter is inputed then detectarClase () should be called as argument with IP string.

This .ino code: 

  #include & lt; Wire.h & gt; # Include & lt; LiquidCrystal_I2C.h & gt; #include & lt; String.h & gt; LiquidCrystal_I2C lcd (0x20,16, 2); Boolean Borar = Wrong; String ip; String Detectorclose (String IP) {Four Verses [IP. Long ()) IPTotcherRay (var, IP.Length ()); Int num = atoi (var); If (num & lt; 127) return "clance a"; If (num == 127) "Directions reserved"; If (num> 127 & amp; amp; amp; amp; amp; & amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp;; If (num> gt = 192 & amp; nbsp; num & lt; 224) return "clans c"; If (num> = 224 & amp; amp; gender & 240; 240) return "clanes de"; If (num> = 240 & amp; amp; amp; amp;; & amp; nbsp; & lt; 255) return "clans e"; } Zero setup () {lcd.init (); LCD backlight(); pinMode (13, output); Serial.begin (9600); Serial1.begin (9600); } Zero loop () {while (Serial1.available ()) {char caracter = Serial1.read (); // Compobamus El character switch (Character) {default: if (borar) {IP = ""; Lcd.clear (); } LCD. Print (catcher); Delay (125); Borar = Wrong; IP.concat; break; Case '\ r': Case 0x0F: Case 0x0A: Borar = True; Lcd.print (detectarClase (IP)); break; }   
 When I try to compile, I get the following output:  
 
  BluetoothLCD .cpp: string detectorclose (string) in function: Bluetooth LDDPPP: 17: 3: Error: "ipa" bluetooth LCDCPPP: 19:25: before the expected starters: Error: A variety of variations has not been declared in this scope    
 I can not really see how I would like the function Committee should, I can modify it to do?   
 
 
 Try  
  char var [100];   
 Arrays may require continuous size at compile time. I think you have ';' At the end of that line

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...
