The heap consists of blocks. But how do these blocks occur???? Can u explain? thank u)

Question

it is strictly based on data alignment???

Answer 1

I think it depends on the CPU architecture. On a 64 bit machine the memory allocation would be in chunks of 8 bytes.

Padding definitely comes into picture and the processor would definitely like to fetch the values in a single cycle hence even an integer value of 4 bytes will have padding of another 4 bytes and gets stored in the memory.
