5 Memory allocations

In the C and C++ programming languages there are generally three different types of memory allocation that can be used to hold the contents of variables. Other programming languages such as Pascal, BASIC and FORTRAN also support some of these types of allocation, although their implementations may be slightly different.

• Static memory allocations: Fixed location, fixed size.
• Stack memory allocations: Variable location, fixed size.
• Dynamic memory allocations: Variable location, variable size.
