like there is some huge data, which i had stored in array, i had to increment the whole array as i had to increment the whole data, so no doubt if I increment the arra_11 (LSB) then whole data or whole array would be incremented, but if incrementation goes out the range of first location of arra_11 , then if we increment further, the carry would be added to 2nd location?? or at that time we need to increment 2nd location individually??
No. If you increment one element of the array, then that is incremented in isolation - there's no automatic behaviour where it will then start to increment other elements too. That's specialised behaviour, that you'd have to implement yourself.
