Web@Neil: a null pointer constant (prvalue of integer type that evaluates to zero) is convertible to a null pointer value. (§4.10 C++11.) A null pointer value is not guaranteed to have all bits zero. 0 is a null pointer constant, but this doesn't mean that myptr == 0 checks if all the bits of myptr are zero. – Web12. 18 points] The following diagram shows main storage starting at address 0x1000.

Web32MBytes of main memory may not be enough in high-end com-puter systems. Since a fixed amount of memory is integrated on the die, it is difficult to adjust the amount of memory in different sys-tems. In this case, off-chip DRAM may be added to the system to form another memory hierarchy level below the on-chip main memory. WebMar 21, 2015 · The off-chip main memory is DRAM.

However, a compiler is required to convert a literal zero pointer into whatever the system's internal representation of NULL is.

WebThis type of memory, also called main memory or RAM (Random Access Memory), is only used for temporary storage of data. When you restart a computer, it typically wipes the memory entirely.
