What is a primary use of pointers as highlighted in the text?

For arithmetic calculations
To modify the value of a variable indirectly
To define constants
To declare a variable's type

The correct answer is: To modify the value of a variable indirectly

Pointers are used to indirectly access and modify the value of a variable. Unlike the other options, which are unrelated to the primary use of pointers, the primary use of pointers is to store a memory address and use it to access and manipulate data stored in that address. Pointers are not commonly used for arithmetic calculations or to define constants. Additionally, while declaring a variable's type is important for programming, it is not the primary use of pointers.
