Function Details : calloc

void *calloc(size_t nmemb,size_t size) ;

Return Type : void *

New Generic pointer that can point to any data type

Read about return values of calloc function .

1st Parameter Type : size_t

Platform-specific unsigned type for array indices and memory sizes.

1st Parameter

The number of elements to allocate

2nd Parameter Type : size_t

Platform-specific unsigned type for array indices and memory sizes.

2nd Parameter

The size of each element in bytes

The callocfunction in C language dynamicall allocates memory on the heap, initializing allocated bytes to zero.

..

The callocfunction takes 2 parameters:

•
size_t `nmemb`: The number of elements to allocate
•
size_t `size`: The size of each element in bytes

Allocates memory for an array of `nmemb` elements of `size` bytes each, initializing all bits to zero. Returns a pointer to the allocated memory or `NULL` if the allocation fails.

The calloc function return value :

Returns a pointer to the allocated memory if successful, or NULL if the memory allocation fails

Output

This example demonstrates the basic usage of `calloc` to allocate an array of integers. Note that all elements are initialized to zero.
