Allocating memory for a variable in run-time called Dynamic Memory allocation.

Suppose in certain condition, if you would like to allocate some memory based on a value of an variable then we have to go for the Dynamic Memory allocation.

Simply saying, you can allocate in compile time if you know the exact size for a variable, if not you can allocate in runtime based on a runtime value.

There are two other ways:
  • Globally (static arrays declared outside of a function)
  • Locally (declared on the "stack")

There are also ways to allocate "shared memory", which is dynamically memory that other processes can use. There are also a few other, highly nuanced types.
