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. 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 points to a specific memory location in a program
- B. A pointer that stores the address of a function in memory
- C. A pointer that can be used to access the arguments of a function
- D. A pointer that can only be used to call functions that return void
Remarks:
Explanation:
Answer: B
Explanation: A pointer to a function in C is a pointer that stores the address of a function in memory. You can use this pointer to call the function directly, without having to refer to it by name.
- 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.
