Dynamic memory allocation is a powerful concept in programming that allows us to allocate memory at runtime. Unlike static memory allocation, where memory is allocated at compile-time, dynamic memory allocation offers flexibility in managing memory resources based on a program’s specific needs. In this lesson, we’ll explore the syntax of declaring dynamic memory for a single variable, discuss the role of pointers in pointing to memory on the heap, compare static and dynamic memory management, and explore the benefits of dynamic memory allocation for arrays.

Dynamic memory allocation for a single variable

To dynamically allocate memory for a single variable, the new operator is used in combination with the desired data type.
