Question

4. Which of these if statements will evaluate to true? Assume that x = 5, and y = 10.

if(!(y > x) || (x % y == x)) { Debug.Log("True 1"); }

if( true || false ) { Debug.Log("True 2"); }

if((y % x == 0) && (x < y) && (y - x != x)) { Debug.Log("True 3"); }

1 and 2

2 and 3

Answer 1

i have 1 & 2 as the answer

Answer 2

sorry its also in java script

Answer 3

Just 2 is correct

Answer 4

thank you so much

Answer 5

one more for you

Answer 6

9. When would you use an Array while programming?

To conserve variable names by combining them into one variable

To go with a for loop, since they work well together

To represent a chess board and the locations of all of the pieces

All of the above

None of the above

Answer 7

You're welcome, it's like that : I will explain just one example, we will take the 3rd :

if((y % x == 0) && (x < y) && (y - x != x)) {
Debug.Log("True 3");
}

(y % x == 0) --> This mean Y=10 modulo x=5 equal 0, true.
(x < y) --> This mean 5 < 10, true.
(y - x != x) --> This mean (10-5) different than 5, false.
&& --> This means And
So we have (True && True && False) = False.

Good luck.

Answer 8

I think the 2nd, mean to use it with a for loop.

Answer 9

wouldnt you also use an array for combining them into one var

Answer 10

I am not sure if I understand this one well, but usually the array has the same type of data for all its cells, so I really dunno. But I DON'T think so.

Answer 11

I think all of the above

"To conserve variable names by combining them into one variable"
I think it tries to say that instead row1 row2 row3 row4 we can just have row[] array

"To go with a for loop, since they work well together"
well you just go by indexes in for loop

"To represent a chess board and the locations of all of the pieces"
You can represent chess board by 2D array, cell[row][column]

Answer 12

if(!(y > x) || (x % y == x)) { Debug.Log("True 1"); }
!(10>5) will be false
5 % 10 = 5 because 5 divided by 10 u get 0 and remainder is 5, so this is true
false or true is true
so first is true

if( true || false ) { Debug.Log("True 2"); }
true or false is true
so second is true as well

if((y % x == 0) && (x < y) && (y - x != x)) { Debug.Log("True 3"); }
10 % 5 = 0 10 divided by 5 is 2 and remainder is 0 so this is true
5 < 10 its true
10-5 != 5, 5 equals 5 so its false
true and true and false is false

answer is 1st and 2nd true

Answer 13

Ah yeah 5 % 10 = 5, true, I make a mistake I wrote 5%10 but I was solving 10 % 5 !!!!

Answer 14

its only 2

for in 1
both statements must be false for in "or statements" one becomes true then everything is true there is this ! sign which will alternate the sign so imagine it like this !x == true||1
x should be 0 or FALSE so if it is inverted it will result to a 1 or true

in number 3 it is an and statement if one statement fails then the statements under that certain condition will be skipped. it was skipped for (y - x != x) which is 10 - 5 != 5
we all know that 10 - 5 == 5 so its FALSE

So the ANSWER is "2"

xD hope it's clear to you xD

Answer 15

@lemuelpogi

dont forget ! has biggest priority..

Answer 16

1 & 2

Answer 17

it has the highest priority but it will look to it later on after the operations and or etc.

Answer 18

no it wont because you said urself it has highest priority, if you don't believe type it in any programming language and see it urself

Answer 19

i mean operations will be calculated then the comparisons like = <> etc. then the and or

Answer 20

but ! has higher priority than = < > and higher priority than 'and' 'or'

Answer 21

it has a higher priority but it is used as getting only the inverse after calculating the answer on either sides xD

Answer 22

no its used as soon as you can since it has highest priority, so you evaluate whats in brackets and then immediately inverse it
(10>5) is true
!(10>5) is false

Answer 23

that's quite true xD

Answer 24

so ur answer is incorrect then

Answer 25

huh? in which part??? ITS TRUE

Answer 26

so u saying that 5%10==5 is true?

Answer 27

yes definitely you can not divide 5 by 10 so its a remainder xD

Answer 28

wait

Answer 29

u said that true is only 2, but first one is true too so thats why u were incorrect

Answer 30

false or true is true

Answer 31

1 and 2 will evaluate to true.
because y>x will be true but due to ! it will be false.
x%y evaluates to 5 and 5==5 will be true.
Since both the expressions are connected by OR.So the result will be true.
The second case is same as first.

Answer 32

only 2

Answer 33

@cs_elis prove it

Answer 34

u r write @Tomas.A i made 10 mod 5
and its the opposite

Answer 35

1 - 2 true
