What is answer of the following code: x=7 x-7 x=4 x-4

doesn't match any syntax I know.

Is that supposed to be two separate statements?
x = 7x-7
x = 4x-4
???
Not knowing x, it's hard to say what the final value will be.
Is that supposed to be four statements?
x = 7
x-7
x = 4
x-4
If so, the 2nd and 4th don't do anything. Final result: x = 4
Maybe it's two assignments and two display statements. Result:
display 0
display 0

Maybe you can be a bit more specific...

Four statements and...

umm the options are:
a)7
b)-7
c)4
d)-4
e)0

To find the answer to the code, let's go step by step:

1. x = 7: This line assigns the value 7 to the variable x.

2. x - 7: Here, we subtract 7 from the current value of x.
Since x is initially set to 7, the result is 0 (7 - 7 = 0).

3. x = 4: This line updates the value of x to 4.

4. x - 4: Now, we subtract 4 from the updated value of x, which is 4.
The result is 0 (4 - 4 = 0).

Therefore, the final answer to the code is 0.
