- A. A pointer can be dereferenced to access its value
- B. A regular variable cannot be passed to a function
- C. A pointer can only store integer values
- D. A regular variable does not require initialization
Remarks:
Explanation:
Answer: A
Explanation: A pointer allows you to indirectly access the value of a variable by dereferencing the pointer with the * operator. A regular variable can be accessed directly with its identifier.
- A. <code>int x = &y;</code>
- B. <code>int *x = y;</code>
- C. <code>int &x = y;</code>
- D. <code>int *x = &y;</code>
Remarks:
Explanation:
Answer: D
Explanation: The correct way to declare a pointer to an integer variable in C is to use the * operator in the declaration, and assign the address of the variable using the & operator.
- A. A pointer that points to a non-existent memory location
- B. A pointer that has not been initialized
- C. A pointer that points to the first memory location in the system
- D. A pointer that points to the end of the system memory
Remarks:
Explanation:
Answer: A
Explanation: A NULL pointer in C is a pointer that points to a non-existent memory location. It is typically used to indicate that a pointer does not currently point to a valid object.
- A. Performing arithmetic operations on the values of pointers
- B. Performing arithmetic operations on the memory addresses stored in pointers
- C. Converting pointers to integers and performing arithmetic operations on them
- D. Converting integers to pointers and performing arithmetic operations on them
Remarks:
Explanation:
Answer: B
Explanation: Pointer arithmetic in C involves performing arithmetic operations on the memory addresses stored in pointers. For example, you can add or subtract an integer value from a pointer to move it to a different memory location. However, it is important to be careful with pointer arithmetic to avoid accessing invalid memory locations.
- A. A pointer that can point to two different memory locations
- B. A pointer that stores a floating-point value
- C. A pointer that points to another pointer
- D. A pointer that can store two integer values
Remarks:
Explanation:
Answer: C
Explanation: A double pointer in C is a pointer that points to another pointer. It is typically used for dynamic memory allocation, where the first pointer points to a dynamically allocated memory block and the second pointer points to a specific location within that block.
- A. A const pointer cannot be dereferenced, while a pointer to a const can
- B. A const pointer cannot be reassigned to point to a different memory location, while a pointer to a const can
- C. A const pointer points to a const object, while a pointer to a const can point to a non-const object
- D. A const pointer and a pointer to a const are equivalent in C
Remarks:
Explanation:
Answer: C
Explanation: In C, a const pointer points to a const object, which means that the object it points to cannot be modified through the pointer. On the other hand, a pointer to a const can point to a non-const object, but it cannot be used to modify that object.
