Explain the use of malloc function in C programming? C malloc() method “malloc” or “memory allocation” method in C is used to dynamically allocate a single large block of memory with the specified size. It returns a pointer of type void which can be cast into a pointer of any form. It initializes each block with a default garbage value. Syntax: ptr = (cast-type*) malloc(byte-size) For Example: ptr = (int*) malloc(100 * sizeof(int)); Since the size of int is 4 bytes, this statement will allocate 400 bytes of memory. And, the pointer ptr holds the address of the first byte in the allocated memory. Description The C library function void *malloc(size_t size) allocates the requested memory and returns a pointer to it. Declaration Following is the declaration for malloc() function. void * malloc ( size_t size ) Return Value This function returns a pointer to the allocated memory, or NULL if the request fails If space is insufficient, allocation fails and r...
