1.a. The Sarah Byrd Askew library has just hired you as chief 
     programmer for their collection.  Write a struct statement 
     to define a structure data-type (called book) which will 
     store a library card catalog entry for a book, including:
       author,   title,  publishing company,  year of publication,   
       ISBN number,  Library of Congress number,  dewey-decimal entry.  
   




1.b. Creat an array (called shelf) of 100,000 of those 
     book struct's.


 

1.c. For the array in 1.b. (above), write all assignment 
     statements needed to fully set the 200th book in the 
     shelf to the Dietel & Dietel book (including all fields).



1.d. Write the prototype and function call which will 
     call a routine called sort which will sort this array
     and return it to the main program. 
     Do not write the whole function.  Be careful and meticulous. 

     prototype: 



     function call: 




2.a. Write a struct (called point) which will define a 
     point <x,y> in the Cartesian plane. 



2.b. Write a struct which will store a triangle (call it tri)
     using only the data-types from part 2.a. (above) 



2.c. Write the code needed to creat a variable (called bermuda)
     of type tri, allocating memory for an actual triangle.
 



2.d. Write a macro    dist(x1,y1,x2,y2)
     which will compute the distance between two points.




2.e. Write the 4 lines of code which uses the macro in 2.d. (above)
     to compute the perimeter of the bermuda triangle from 2.c.
