in this video, each memory cell is of 1 byte i.e 8 bits and 5–>101 takes 3 bits in 1-byte cell( out of 8 bits) so if it is updated to 15–>1111 means 4 bits (which is already present out of 8bits)
so why we need to allocate? also, 101 is 3 bits number which still can occupy 4 bits as per int range, then why allocate the memory?
Memory allocation example
hello @sakshi.saxena
no is not like that,
if a variable takes 1 byte then it will always take 1 byte,irrespective of its content.
example if i say that int datatype takes 1 byte (just an example)
then if will not matter what number i am storing , always one byte space will be used,
