How to get the Size

[rachelle]

I am starting my try with memory allocation dynamically in C programming language. I have a doubt namely how to find at run-time the size of a dynamic memory allocation and this is an array. Kindly suggest some alternatives for achieving the size.

[Mukhtar Ahmad]

memory allocation dynamically is done by
malloc() and calloc() functions in C language

provide any example how you want the memory allocation dynamically?

Memory is dynamically allocated in c by using malloc(), calloc() and realloc().

void * malloc(size_t size);
The malloc() function takes size_t as its argument and returns a void pointer. Void pointer is used because it can allocate memory for any type.
Just store the size in a variable the same way that we are're storing the pointer in a variable and a struct can be used to put them both together.
