Answer Posted / priya
The malloc function allows the programmer to create a block of memory of a given size:
malloc ( long integer lBlockSize ) returns void *
If we decide, during the execution of the program, that we might need to expand, or contract this memory block, we can use the realloc function:
realloc ( void * pBlock, long int lNewBlockSize ) returns void *
When the memory block is no longer used, then it must be returned back to the operating system, by calling the free function:
free ( void * pBlock )
