Compilation error: missing terminating ' character

beast2274 · April 23, 2024, 8:25pm

So I have a compilation error and was wondering if anyone could help me fix it!
I am using a arduino mega

so this is the highlighted error part :

Serial.print('

'); for(int i = 0; i < 3; ++i) { int val = EEPROM.read(4 + i); if(val < 16) Serial.print('0');

Serial.print(val, HEX); } Serial.print(' '); for(int i = 0; i < 64; ++i) { int val =

EEPROM.read(4 + 3 + i); if(val < 16) Serial.print('0'); Serial.print(val, HEX); if((i & 3) ==

Serial.print(' '); } Serial.print(' '); }

and here is a screenshot of it:

Please insert the code using code tags. The images of the code are useless.

beast2274 · April 23, 2024, 9:22pm

i'm hoping this is better and im sorry for my lack of etiquette.

 Serial.print('
'); for(int i = 0; i < 3; ++i) { int val = EEPROM.read(4 + i); if(val < 16) Serial.print('0'); 
Serial.print(val, HEX); } Serial.print(' '); for(int i = 0; i < 64; ++i) { int val = 
EEPROM.read(4 + 3 + i); if(val < 16) Serial.print('0'); Serial.print(val, HEX); if((i & 3) == 
3) Serial.print(' '); } Serial.print(' '); }

i dont know if this helps or if im doing it correctly, im a newb just trying to get some help making this code work. thank u for any and all help!!

 Serial.print('

'); for(int i = 0; i < 3; ++i) { int val = EEPROM.read(4 + i); if(val < 16) Serial.print('0'); 

Serial.print(val, HEX); } Serial.print(' '); for(int i = 0; i < 64; ++i) { int val = 

EEPROM.read(4 + 3 + i); if(val < 16) Serial.print('0'); Serial.print(val, HEX); if((i & 3) == 

3) Serial.print(' '); } Serial.print(' '); }

beast2274 · April 23, 2024, 9:57pm

i dont know if im doing it right or if this helps but u tell me!

Serial.print('

'); for(int i = 0; i < 3; ++i) { int val = EEPROM.read(4 + i); if(val < 16) Serial.print('0'); 

Serial.print(val, HEX); } Serial.print(' '); for(int i = 0; i < 64; ++i) { int val = 

EEPROM.read(4 + 3 + i); if(val < 16) Serial.print('0'); Serial.print(val, HEX); if((i & 3) == 

3) Serial.print(' '); } Serial.print(' '); }

Please post complete code using the code tags. People should be able to try to compile your code and see the same error. I would advise you reformat you code to have only a single statement on each line. In the ide window use edit > auto format to make it easier to see what is going on.
Post the complete error message. Click on the quotation marks at the top of the reply window and post the text after the blockquote >

gfvalvo · April 23, 2024, 10:02pm

That's an unholy mess. Take a look at the example code in the Arduino IDE. You'll see NONE of it is formatted like that.

lastchancename · April 23, 2024, 10:13pm

First lesson…
The C class languages are heavily dependent on whitespace to process the source code structure.

So far you have obviously not absorbed that fact, nor have you followed suggestions from the helpers.

We can’t help you, if you don’t help yourself.

i auto compiled it and than copied the whole error message and thanput it after the blockquote

copied the whole error message

Good job.

Now where is the complete code posted using the code tags?

@Delta_G

that worked!!

YESSSSSS! thank you soooo much it worked!!!! thank you thank you thank you !!

Sketch uses 6714 bytes (2%) of program storage space. Maximum is 253952 bytes.
Global variables use 2061 bytes (25%) of dynamic memory, leaving 6131 bytes for local variables. Maximum is 8192 bytes.

Do you understand why? I ask, because if you don't...you'll be back.

beast2274 · April 23, 2024, 11:12pm

I believe so I can't start a line in the middle of the parentheses I get that and all I needed was this one sketch so all the help thank you so much!

DaveX · April 24, 2024, 12:09am

You can start a line in the middle of parentheses, just not in the middle of a character.

See:

and

camsysca · April 24, 2024, 2:46am

no. The issue is, two single quotes, ', should have between them a single character. In your case, you have

'crbbbbbbbbb'

where cr is a carriage return, and the bbbbbbbb after it is the space characters required for text alignment in the IDE.
