Lab Assignment 2

PLS NOTE: The text typed in the objects in the diagram, which correspond to textboxes in the table, is just done for you to be able to map objects between the table and the diagram. All textboxes (and only textboxes not buttons and labels) must appear blank in your application (like they do in a real calculator). Buttons and labels should display the symbols/words that are displayed on them in the diagram.

A) Simple Calculator

Object	Name	Function
1. Textbox	txtInput1	Takes the first input from the user
2. Textbox	txtInput2	Takes the 2^nd input from the user
3. Button	btnAdd	When clicked -> adds the 2 user inputs
4. Button	btnSubtract	When clicked -> subtracts the 2 user inputs
5. Button	btnMultiply	When clicked -> multiplies the 2 user inputs
6. Button	btnDivide	When clicked -> divides the 2 user inputs
Label	lblResult	Displays the result of the operation

B) Grade Calculator

Weighted Average: An average that takes into account the proportional relevance of each component, rather than treating each component equally.

Object	Name	Function
1. Label	lblGrade	Displays title “Grade”
2. Label	lblWeight	Displays title “Weight”
3. TextBox	txtGrade1	Takes the homework grade input from user
4. TextBox	txtGrade2	Takes the midterm grade input from user
5. TextBox	txtGrade3	Takes the finals grade input from user
6. TextBox	txtWeight1	Takes the homework weight-age
7. TextBox	txtWeight2	Takes the midterm weight-age
8. TextBox	txtWeight3	Takes the finals’ weight-age
9. Label	lblHomework	Displays title “Homework”
10. Label	lblMidterm	Displays title “Midterm”
11. Label	LblFinals	Displays title “Finals”
12. Button	btnFinalGrade	When clicked-> computes the final grade
13. Label	lblResult	Displays the result of the computation(both the computed value and the corresponding letter grade eg. 93=A)

Rules for Grade Calulator:

1. The grades must be inputted as values between 0-100.

2. The weights must add up to 100.

3. A weighted averge must be computed for the final grade ie.

(Grade1*Weight1 + Grade2*Weight2 + Grade3*Weight3)/(Weight1+Weight2+Weight3) and the result must be converted back to a grade A(90-100),B(80-89),C(70-79), D(40-60),F(0-40) and displayed along with the numeric value of the grade eg. 93 = A.
