malloc: allocate memory


    

//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;
  }
