Transcribed Image Text:## Understanding the Address Operator
In computer programming, particularly in languages like C and C++, the address operator is a fundamental concept.
### Question: The address operator
- ○ is a variable that holds an address
- ● all of these
- ○ returns the memory address of a variable
- ○ dereferences a pointer and allows access to the value of the variable the pointer points to
The address operator, represented by the ampersand (&), is used to obtain the memory address of a variable. Here’s a breakdown of its roles:
1. A variable that holds an address: Often referred to as a pointer, it stores the memory address of another variable.
2. Returns the memory address of a variable: By using the & operator before a variable, you can get its memory address.
3. Dereferences a pointer: By pointing to the memory address, we can access the value stored at that address.
In the provided question, the correct answer marked with a filled-in circle (●) is "all of these," signifying that all the statements provided are accurate descriptions of the roles of the address operator.
