What is the size of a pointer to an int (on a 64-bit architecture)8 bytes2 bytes4 bytes1 byteI don't know

To determine the size of a pointer to an int on a 64-bit architecture, it's important to understand how pointers work in this context:

1. Pointer Size in 64-bit Architecture: In a 64-bit architecture, pointers are designed to hold memory addresses that are 64 bits wide. This implies that every pointer requires a specific amount of memory to store these addresses.

2. Standard Pointer Size: Regardless of the type of data the pointer is pointing to (whether it's an int, char, or a struct), the size of a pointer itself is consistent, determined by the architecture, not the data type.

3. Conclusion:

   • In a 64-bit architecture, the size of a pointer is typically 8 bytes.

Final Answer

The size of a pointer to an int on a 64-bit architecture is 8 bytes.
