Duration : 6:00pm - 8:30pm

	We met at the room of our team leader(siyar).We analysed the 1st phase of our programming.Our aim for the 1st submission was to convert the infix expression entered by the user to a postfix expression.We had downloaded a code which did the same and we analysed the code to try and understand the logic used.Our task was made considerably difficult by the fact that the program had no comments in it.We searched the net for the program's logic finally we were able to understand the code.
	But there were a few flaws in the code:
1.The code didnt execute correctly when '-' or '^' symbol was entered.
2.There were no comments in the code.
3.There were no indentations in the code.
4.There was a small errror in the code when both '+' and '-' were included.
We indented the program suitably and disbanded for the day.

Duration : 6:00pm - 8:30pm

	We assembled again at our team leader's room.We succeeded in doing the following tasks:
1.Read through the program carefully and added a few lines of code.Upon reexecution the program worked perfectly.The flaw lied in the preference orders where these 2 symbols werent mentioned.
2.We inserted suitable comments at all possible places.
3.By changing the preference orders of '+' and '-' we were able to overcome our 4th problem.

We are still faced with the following problems:
1.Only algebraic expressions can be evaluated.
2.We dont know how to pass a postfix expression to the computer for evaluation.

Our targets for the next phase are:
1.Try and include non algebraic expressions.
2.Try to find a way to pass the postfix expression to the computer.
3.Plot the graph.
