In the context of C++, which statement about pointers is true?

Pointers in C++ are a fundamental concept that allows developers to directly interact with memory addresses. The statement that they store the address of a variable is true because the primary purpose of a pointer is to hold the memory address where a variable resides. This characteristic enables various important features such as dynamic memory allocation, passing variables by reference to functions, and managing arrays and other data structures efficiently.

For example, when you declare a pointer to an integer, the pointer variable will store the address of an integer variable. This storage allows you to manipulate the integer value by dereferencing the pointer, thereby altering the actual value stored in memory.

The other options present limitations or misconceptions about pointers. Notably, pointers are not restricted to pointing only to integer types; they can point to any data type, including char, float, and user-defined types. Also, pointers can indeed work with arrays because the name of an array acts as a pointer to its first element, allowing pointer arithmetic and easy access to array elements. Lastly, pointers can be associated with both static and dynamic variables, meaning they are not limited solely to static variables. This versatility makes them a powerful tool in C++.
