How to write C code in Keil MICRO VISION3 to jump to Interrupt Vector when interruptoccurs? (While writing code in C we are not mentioning anyRAM/ ROM address)
But, whether you read it online or offline, you must learn to make the manuals your first point of call.
To emphasize Andys point think about the average time it takes to find something in the manual (seconds) vs the time it takes to get a reponse in the forum (hours).
Yes, it is 'easier' to post a question than to search in the boring book, but do you want to put what you are doing aside till you get an answer?
Of course, if you hate your job/your boss you can post a question, sit back and twiddle your thumbs and when asked "why are you not doing anything" answer "I have posted a question, can do nothing till I get an answer"
