arry with loops

how to Check if the array is equal. Two arrays are
equal if their sizes are same, and elements with same index from both arrays are same.  Display both arrays.  Display if the array is equal or not equal. no one was able to answer this question any help (edited)

yes its in my uni and need to do it with loop

no one was able to answe it

the teacher said set your own arry value

array*

this is the full q

from the array it self

like the length

count

so array from 0

but the value in it start from 1

Do you know how to get the length?

int[,] arr = ( (1, 2, 3), (4, 5, 6 ), ( 7, 8, 9} };

for example this got 2 array

Right ?

0 1 2

yes i know

this one i dont know

i don’t know how to compare vvalues

Are you actually trying to do this for multi-dimensional arrays?

Maybe i can declare tow array then loop them?

if(int x= 5; )

wait wait let me try

shit i give up

oh yaaaaa

yes yes

let me try

First i will declare toe arrays

then i will do the calculation u ask me

wait please

but i am confused

there is tow type of array

which one i declare

What do you mean exactly?

type 1.....int[,] arr = new int[,]{{1,2,3},{4,5,6},{7,8,9}};

type2...• int[] arr = new int[5]{ 10, 20, 30, 40, 50 };

how i knows in he future if he want the first type?

2d array?

Multi-dimensional arrays are kind of special purpose - like for defining a grid or matrix.

Most uses of arrays are the single dimensional kind.

int[] arr = { 10, 20, 30, 40, 50 };

int[] arr1 = { 5, 22, 63, 70, 80 };

if(arr == arr1)
System.Console.WriteLine("they are equal");

else
{
System.Console.WriteLine("they are not equal");
}

this better

Unfortunately this way of checking array content's equality wouldn't work in c#

i am using Visual Studio

then how to make it work in c#

ohhhh

yes in this uni must Visual studio code

i had long dilemma with the teacher end up his winning and my lost lol

hmmm i am confused how to do thta

that

yes

ohhhh so array cant because not specific number

yes there is

arr.length ?

but how to cod it nicely

let me try

like that?

feels wrong

i try this too

but obviously wrong

hard life

In an if statement you'll do

(expression) == (expression) expression here can be any value or variable

So the first expression you have is
arr=arr.Length
second expression
arr1=arr1.Length

What these expressions mean
They mean assign arr.Length to arr
and assign arr1.Length to arr1
That obviously wouldn't work because
1- arr1 and arr1.Length have different types
2- the expressions can't be compared

i am just a little confused now lol

then how

now?

it must be this Visual headache i kill u slowly program

if {} ?

so if can be () and {}

what is the difference ?

i notice for loop (FOR) always ()

like this

ok ok noted

and elements with same index from both arrays are same.

what is that

i don’t understand index,

ohhhhh

i have an idea yea

so in q want me to delete.

i didn’t know that

the rest of the q

yes i am trying

is this real person ?

ok following u

if ?

if(arr[0] ==arr1[0]); ?

heheh u are amazing teacher

ok

ohhh yea yea

then how

for(int a=0; a=<5; a++)

yes sooo ok

for(arr[,]=0; arr[,]=>....... i can’t figure the rest

nested loop ?
