malloc: allocate memory

<source lang="cpp">

//Declaration: void *malloc(size_t size); //Return: returns a pointer to the memory.

              If there is insufficient memory, malloc() returns a null pointer. 
 
 #include<stdio.h>
 struct addr {
   char name[40];
   char street[40];
   char zip[10];
 };
 main()
 {
   struct addr *p;
   p = malloc(sizeof(struct addr));
   if(p==NULL) {
     printf("Allocation Error\n");
     exit(1);
   }
   return p;
 }
