Midterm and introduction to correctness of a program

 The midterm was quite good,however i screwed up royally on one of the questions,while doing quite well on the remaining two.An overall estimation of my performance was that i knew what i was doing for the most part,i just did not follow through.hopefully,this will enable me to do better on the 2nd test.We began doing the correctness of a program this week,which was confined to two important properties,the precondtion which states what sort of input is needed for the program to be 'correct',and the postcondition,which states what sort of output stipulates a 'correct'program.Very interesting stuff.The other order of buisness is Assignment 2.Having done exceptionally well on A1, i now have to emulate the standard i have set myself on this assignment.
