1. ### Break Down the Problem

The question asks for the format specifier that returns the memory address and its format type.

2. ### Relevant Concepts

In C and C++ programming, format specifiers are used in functions like printf to define how data should be formatted. %p is commonly used to output a memory address, and it generally returns the address in a hexadecimal format.

3. ### Analysis and Detail

• %p: This is the format specifier for pointer addresses. When using %p in a printf statement, it will display the address stored in a pointer variable.
• The address is typically represented in hexadecimal form. This is because memory addresses are most conveniently expressed in base-16 notation.

4. ### Verify and Summarize

After reviewing common usage of format specifiers in C and C++, the correct answer can be confirmed as follows: the format specifier for memory addresses is %p, and it outputs the address in hexadecimal format.
