1. Have a look at the sampleio file for some sample inputs & outputs
2. Your output should be as specified in the assignment: The start vertex should be the one with the largest y coordinate and the traversal order should be clockwise
3. Your program should read input from stdin (the console) and write output to stdout (the console)
4. DO NOT prompt for n, points or print statements like "Enter the value of n", etc
5. Do not worry about white space in your output, but follow the format specified
6. Name your program prog1.cpp
7. Turnin your code using the command: turnin prog1@cs130b <files>

Note: Format all floating point values upto 4 decimal places. You can use printf(".4f",value) to do that
