Solutions for selected sample questions:

SAMPLE FINAL VAR 1 : Circle

/* SAMPLE FINAL  1 VAR 
  (a) Input the radius of a circle using fscanf(); 
  (b) Write one function to calculate the area (pi*r*r) and circumference (2*pi*r) of the circle
   (note that you will need to use pointers in the function (if you don't use records)).
  (3) print  using fprintf() the radius, area and circumferance 
  (NOTE: This is not good programming style)
*/

SAMPLE FINAL FLOW 1 : Biggest and Smallest

/* SAMPLE FINAL  2 FLOW Write a program that 
  (1) Prompt the user and read four positive integers (fixed-point);  
  (2) Call a function big() to return the largest integer.  
  (3) Call a function small() to return the smallest integer
  (4) Print the largest and smallest integers using fprintf() 
*/ 

SAMPLE FINAL ARRAY 1 : Biggest and its Index

/* SAMPLE FINAL  3 ARRAY Write a program that 
   (1) reads 6 positive integers into an array  b[]
   (2) call a function big() to return the index of the array which 
        contains the largest integer
   (3) Print the index of the array and value stored at this location.
*/

SAMPLE FINAL RECORD 2 : Circle

/* SAMPLE FINAL  4 RECORD (Based on SAMPLE FINAL 1 VAR) 
  (a) Define a record to hold the radius, area, and circumference of a circle.
  (a) Input the radius of a circle using fscanf(); 
  (b) Write one function to calculate the area (pi*r*r) and circumference (2*pi*r) of the circle.
  (3) print using fprintf() the radius, area and circumferance
