Question

Q1. Write JavaScript program to add functionality to the simple calculator. Make sure your program includes these features. 1. Before you start working on your code, look at the data file given and see how things are placed, id's or names or class. 2. As the different keys are clicked the values are displayed in the screen as shown (1+2) 3. Once the = key is clicked, your program reads the expression and performs the operation and displays the result in the screen. 4. Your program should work for any expression and order of operations maintained. Ex. If the expression is 6/3+52-1 = 11(/\n& first then addition and subtraction) 5. No two operators should be added consecutively. (no two operator keys clicked consecutively) 6. The equation shouldn't start from an operator except minus 7. Assume that only integer numbers are given. 8. If the c (clear) key is clicked, clear the screen. 9. Not allowed to use the eval function 10. Add documentation in your code.

Make sure your program includes these features.
1.
Before you start working on your code, look at the data file given
and see how things are placed, id's or names or class.
2.
As the different keys are clicked the values are displayed in the
screen as shown (1+2)
3.
Once the = key is clicked, your program reads the expression
and performs the operation and displays the result in the screen.
4.
Your program should work for any expression and order of
operations maintained. Ex. If the expression is 6/3+5*2-1 = 11(/\n&* first then addition and subtraction)
5.
No two operators should be added consecutively. (no two
operator keys clicked consecutively)
6.
The equation shouldn't start from an operator except minus
7.
Assume that only integer numbers are given.
8.
If the c (clear) key is clicked, clear the screen.
9.
Not allowed to use the eval function
10.
