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

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
