The Malloc ( ) Function

The malloc function allocates a block of memory in bytes. The user should explicitly give the block size it requires for the use. The malloc function is like a request to the RAM of the system to allocate memory if the request is granted (i.e.. the malloc function stays successful in allocating memory) returns a pointer to the first block of that memory. The type of the pointer it returns is void which means that we can assign it any type of pointer. However if the malloc( ) function fails to allocate the required amount of memory it returns a NULL The malloc ( ) function is available in header file alloc h in TURBO C and on UNIX it will be available in header file <malloc.h> The syntax of this function is an follows :

               Malloc (number of elements*size of each element):

For example,

               Int *ptr ;

              Ptr=malloc (10*sizeof(int))
