Question
How do you declare a constant pointer to an integer in C?
Options:
int *const ptr;const int *const ptr;const int *ptr;int const *const ptr;
Solution
To declare a constant pointer to an integer in C, we need to ensure that the pointer itself cannot be changed to point to another integer, while the integer value being pointed to can still be modified.
The correct declaration for a constant pointer to an integer is:
- *int const ptr;
In this declaration:
intsignifies that the pointer points to an integer.*constindicates that the pointer's address cannot be changed after it is initialized.
Thus, while you can change the integer value that ptr is pointing to, you cannot change what ptr points to.
Final Answer
The correct answer is: int *const ptr;
