POINTERS

POINTERS. Pointers. A pointer type is one in which the variable has a range of values corresponding to memory addresses and a special value, nil, which means an invalid address. Pointers: design issues. What is the scope and lifetime of a pointer variable?

Memory Leaks and Dangling Pointers

Memory Leaks and Dangling Pointers. Lecture 5 Secs 2.4, 3.4 Mon, Jan 28, 2008. Memory Leaks. A memory leak occurs when all pointers to a block of allocated memory have been lost. Leaked memory cannot be accessed or reallocated.
