In C, which of the following is true regarding pointers?

Pointers in C are a fundamental part of the language that allow for dynamic memory management, manipulation of arrays, and efficient function argument passing. The assertion that pointers hold the memory address of another variable is the essence of what pointers do in C programming. A pointer is essentially a variable that contains the address of another variable. This allows programmers to access or manipulate the value of that variable directly in memory, which can lead to greater efficiency and flexibility in code.

For example, if you declare an integer variable and then create a pointer that points to that integer, you can modify the integer's value through the pointer. This ability is crucial for a number of programming scenarios, such as dynamically allocated memory, where you may not know the size of the data you need at compile time.

The other options focus on misconceptions about pointers. For instance, pointers are not restricted to storing integer values; they can point to any data type, including structures, characters, and user-defined types. Additionally, pointers are not limited to arrays; they can be used with any data type and for various purposes, such as linked lists, trees, and more. Finally, once a pointer is assigned an address, it can indeed be dereferenced to access or modify the value stored at that
