I need a solution ASAP please

Problem 3: Memory management The iOS _MALLOC(size_t size, int type, int flags) function allocates size bytes on the heap. Internally blocks are represented as a length field followed by a data field: struct mhead { size_t mlen; char dat [0]; The mlen field is used by the free() function to determine how much space needs to be freed. In iOS 4.x the _MALLOC function was implemented as follows: 1 void * _MALLOC (size_t size, int type, int flags) { 2. struct mhead *hdr; 3 size_t memsize = sizeof (*hdr) + size; 4 hdr = (void *) kalloc (memsize); // allocate memory 5 hdr->mlen = memsize; 6 return (hdr->dat); 7 } In iOS 5.x the following two lines were added after line 3: int o = memsize
