Did you write some code?

[Ali Salih]

no,I need code of this quetions

x=round(rand()*1000);
disp(['the random number is :' num2str(x)])
if x>100
    if rem(x,2)==0
        y=x/4;
        disp(['the random number is even and greater than 100, answer is :' num2str(y)])
    else
        disp('the random number is greater than 100 but not even number')
    end 
else 
    disp('the random number is not greater than 100')
end

Answer 1

[KSSV]

1. To generate randomnumber read about randi.
2. To check whether even or not use mod. Read about mod.
3. To check whether greater or not, read about inequalitites.

[Ali Salih]

can you write code ?

[KSSV]

Yes.

[Ali Salih]

I appriciate you if you write this code

[Rik]

KSSV could write the code for you, but what would you learn? Read the link Madhan posted.

[KSSV]

With the given hints, it is your duty to read and code it.

[Ali Salih]

i don't no yet what is the wrong??

[Ali Salih]

this answer is corret

x=round(rand()*1000);
disp(['the random number is :' num2str(x)])
if x>100
    if rem(x,2)==0
        y=x/4;
        disp(['the random number is even and greater than 100, answer is :' num2str(y)])
    else
        disp('the random number is greater than 100 but not even number')
    end 
else 
    disp('the random number is not greater than 100')
end

[KSSV]

% x=round(rand()*1000);
x = randi(1000,1) ; 
fprintf('the random number is : %d\n',x)
if x>100
    if mod(x,2)==0
        fprintf('the random number is even and greater than 100\n') ; 
    else
        fprintf('the random number is greater than 100 but not even number\n')
    end 
else 
    fprintf('the random number is not greater than 100\n')
end

[Ali Salih]

where is the divide by 4

[KSSV]

If you want it you can include it..

[Ali Salih]

ok, tanks a lot

Answer 2

[Sysy Gdhhdys]

clc;clear all;

x=randi([100,1000]) ;
disp(['the random number that is between 100 and 1000 is ( ' num2str(x) ')'])

the random number that is between 100 and 1000 is ( 825)

if x>500;
    
    disp('the number is greater than 500')
    
    x2=~mod(x,2);
    x3=x2*x;
    x4=x3/4;
    
    if x4==0;
        disp('the number is odd')
        
    else
        disp(['that number is even and greater than 500 we divided by 4 is equal to (' num2str(x4) ')'])
    end
    
    
    
else
    disp('the number is not greater than 500')
    
    
end

the number is greater than 500

the number is odd
