Final answer:
A pointer holds the memory address of another variable called the pointee, and does not contain the actual data but the location of the data. Dereferencing a pointer accesses the actual data at the memory address it points to.
Step-by-step explanation:
The relationship between a pointer and a pointee is a fundamental concept in computer programming, particularly in languages such as C and C++. A pointer is a variable that holds the memory address of another variable, which is known as the pointee. The pointer does not contain the actual data, but rather the location of the data. When you dereference a pointer, you are accessing the data stored at the memory address that the pointer is pointing to.
For example, if you have an integer variable num with a value of 10, and a pointer p that holds the address of num, p is said to 'point to' num. When you use the dereferencing operator (*) on p (i.e., *p), you are accessing the value of num through the pointer. In this relationship, p is the pointer and num is the pointee.
