C# and Python

1. CS Final Project 2010 Rohan Paramesh C# and Python

2. The Programs • Implementing 3 programs each in C# and Python • Student Scheduler • Assigns courses and students, sorts according to different criteria • Twenty Questions • A binary tree of QuestionNodes that writes out to and reads from a text file • Towers of Hanoi • Recursively provides a solution to the puzzle

3. C# • Microsoft’s current language • Compiled • Java-like • Syntax • Logic • An atmosphere of whatever Java got wrong is fixed in C#

4. Python • Guido van Rossum • Emphasis on readability • Significant differences • Logic • Style • Syntax • Very popular nowadays with amateur developers and some large companies • Google

5. Towers of Hanoi Java C# public static void solveHanoi(int disks, int from, int other, int to) { if (disks <= 0) return; solveHanoi(disks-1, from, to, other); System.out.println("Move disk " + disks + " from pole " + from + " to pole " + to + "."); moves++; solveHanoi(disks-1, other, from, to); } public static void SolveHanoi(int disks, int from, int other, int to) { if (disks <= 0) return; SolveHanoi(disks - 1, from, to, other); Console.WriteLine("Move disk " + disks + " from pole " + from + " to pole " + to + "."); moves++; SolveHanoi(disks - 1, other, from, to); }

6. Towers of Hanoi Java Python public static void solveHanoi(int disks, int from, int other, int to) { if (disks <= 0) return; solveHanoi(disks-1, from, to, other); System.out.println("Move disk " + disks + " from pole " + from + " to pole " + to + "."); moves++; solveHanoi(disks-1, other, from, to); } def solve_hanoi(disks, start, other, dest): '''The main recursive method that solves the Tower of Hanoi puzzle. This method calls itself and also increments the number of moves. disks -- the number of disks (integer) start -- the starting peg (determined by class constant) other -- the intermediate peg dest -- the destination peg ''' if (disks <= 0): return solve_hanoi(disks-1, start, dest, other) print "Move disk ", disks, " from pole ", start, " to pole ", dest, "." global moves moves += 1 solve_hanoi(disks-1, other, start, dest)

7. Comparison • Scope • Methods and Parameters • Types • Compiled vs. Interpreted • I/O • Freedom/Restrictions • Accuracy • Readability
