How to dynamically allocate a structure in C?
Solution: Allocate storage for data dynamically, as needed.
The Standard C Library provides a function for allocating memory at run-time: malloc. void *malloc(int numBytes); It returns a generic pointer (void*) to a contiguous region of memory of the requested size (in bytes).What is dynamic allocation of memory for structure?
Dynamic allocation of memory is a very important subject in C.
It allows building complex data structures such as linked lists.
Allocating memory dynamically helps us to store data without initially knowing the size of the data in the time we wrote the program.Usage example
int array[10]; However, the size of the array is fixed at compile time.
If one wishes to allocate a similar array dynamically without using a variable-length array, which is not guaranteed to be supported in all C11 implementations, the following code can be used: int *array = malloc(10 * sizeof(int));
Why is dynamic memory allocation important in data structure?
Dynamic memory allocation is a process that allocates memory for variables and data structures at runtime, when the program requests it.
This allows for flexibility and efficiency, as the size and location of memory blocks can be changed according to the program logic and data size.
