Chapter 5.3, Problem 16STE
Program Plan Intro
Functions calling functions:
- A function body can contain a call to another function.
- It acts as same as if called from a main function.
- The declaration for function should appear before usage of function.
- In programs all function declarations come after main function.
- A function call can be placed within another function’s definition.
- The definition of one function could not be placed within body of definition of another function.
Precondition and Post conditions:
- A function declaration comment can be written as two types of information that is precondition and post condition.
- When a function is called, the precondition states conditions to be true.
- The function could not be used or perform correctly unless precondition holds.
- The post condition describes function call effect; it states conditions to be true after execution of function where precondition holds.
- The post condition describes value returned by function if it returns one.
- The post condition describes changes made to argument values for a function that may change values of variables.

Write the definition of a function add, which receives two integer parameters and returns their sum.
Give a precondition and a postcondition for the predefined function sqrt, which returns the square root of its argument.
Write a function that takes 3 integers (num,den,power) as parameters which represent the rational number num/den and its power and returns the difference of these two fractions.
(A/B) to the power of n = A to the power of n/B to the power of n
• den can not be zero.
• use simplify function.

B4 Amend your code to keep track of the total number of moves in the game, by writing a function PlayHanoi2 (pos, a, b, c,n, j) which has an additional input j (which will be zero on the initial input) to serve as a move-counter, and which outputs suitably modified (pos, j). Define a function WholeGame2 (n) which runs PlayHanoi2 on a suitable starting configuration. This might be tricky depending on how you coded B3: the danger is that the counting variable j will assume different val- ues in different subroutines. Make sure you keep careful track of the current game position and number of moves throughout your function.arrow_forward
