What is dynamic memory allocation in C?

Can you explain what dynamic memory allocation is in C?

Dynamic memory allocation in C allows you to allocate memory at runtime using functions like malloc, calloc, and free.

Why would I use dynamic memory allocation instead of static allocation?

Dynamic allocation is useful when the size of data structures is not known at compile time, allowing for more flexible memory usage.

What are the common functions used for dynamic memory allocation?

The common functions are malloc() for allocating memory, calloc() for allocating and initializing, and free() for deallocating.

Can you give me an example of using malloc in C?

Sure! Here's a simple example: int *arr = (int*)malloc(5 * sizeof(int)); allocates memory for an array of 5 integers.
