Questions: Assuming a 64 Bit Architecture, int dLists[10] is how many bytes?

To determine the number of bytes occupied by the array int dLists[10] on a 64-bit architecture, we need to consider the size of the int data type on this architecture.

1. Size of int on a 64-bit architecture:

   • Typically, the size of an int is 4 bytes (32 bits) on most architectures, including 64-bit architectures. This is a common standard, although it can vary depending on the specific system and compiler.

2. Size of the array dLists[10]:

   • The array dLists contains 10 elements, each of which is an int.
   • Therefore, the total size of the array in bytes is calculated by multiplying the number of elements by the size of each element.

\[ \text{Total size} = \text{Number of elements} \times \text{Size of each element} \]

\[ \text{Total size} = 10 \times 4 \text{ bytes} \]

\[ \text{Total size} = 40 \text{ bytes} \]

Thus, the array int dLists[10] occupies 40 bytes on a 64-bit architecture.

The answer is: 40 bytes.
