What are these "\002", "\252" I'm observing when debbuging?

(1/1)

Léa Massiot:
Hello,

Thank you for reading my post and sorry for the lame thread title.

I am manipulating bytes arrays like for instance:
 
--- Code: ---char bytesArray[10];
--- End code ---

When I debug my code and visualize the contents of such an array using the C::B "Watch" functionality, I observe such "things" as:
"\002", "\252", etc.

If I do a:

--- Code: ---printf("B0 = %x\n", bytesArray[i] & 0xff);
--- End code ---
where i is the index of the char "\252" in bytesArray,
I get AA16 which is what I'm expecting.

Yet, I don't understand what is this "\252" code. What is it?
Given such a "code", how can I manually get the corresponding hexadecimal and even binary form?
I there a table somewhere? Does this table have a name?

Thank you for helping.
Best regards.

Léa Massiot:
This is octal notation.

Best regards.

Freem:
If you use watches, you can "convert" it to hexadecimal or decimal in it's properties. (right click on the watch, properties, then specify something in format)

Léa Massiot:
All right!
Very good. Thank you :)
