It seems like you're asking about the purposes of a pointer in programming. The most applicable option from the list you provided is:
All of the mentioned options
Explanation:
- To create a new variable: Pointers can be used to dynamically allocate memory for new variables, which can be particularly useful in scenarios where the size of data is not known at compile time.
- To store the address of another variable: This is the primary function of pointers. They are designed to hold memory addresses of other variables.
- To perform mathematical operations: While pointers themselves do not perform mathematical operations, they can be used in expressions to navigate through arrays or data structures, which involves arithmetic on the pointer values.
Thus, using pointers indeed serves all these purposes.
