What are these "\002", "\252" I'm observing when debbuging?
« on: September 16, 2012, 06:07:04 pm »
Hello,

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

I am manipulating bytes arrays like for instance:
 
Code: [Select]
char bytesArray[10];
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: [Select]
printf("B0 = %x\n", bytesArray[i] & 0xff);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.

This is octal notation.

Best regards.

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)
