what loop to use to make the code\input repeat again ?

hello all , i'm new to the matlab and trying to learn so my question is very basic

i have this code for example :

a=5 ;

i = input('choose a number ');

if i == a

disp ('RR');

end

if i~=a

disp ('wrong!' );

end

when the user input 5 it will display a massege , otherwise a diffrenet massege

but it only works once , if i input for example 3 it will display the correct massege , but when i enter any number again nothing happens i have to rerun the code.

how can i fix this ? i want to input any number any number of times with the correct massege appearing without having to rerun the code

Hi,

Matlab support two types of loops, while and for. you can use any of them.

for example using while loop

n=input('Enter number of executions you want: ');
while n>0
    a=5 ;
    i = input('choose a number   ');
       if i == a
         disp ('RR');
       end
       if  i~=a 
           disp ('wrong!' );
       end
       n=n-1;% decrrising n by 1 at every loop
end

and whith for loop

n=input('Enter number of executions you want: ');
for j=1:n
    a=5 ;
    i = input('choose a number   ');
       if i == a
         disp ('RR');
       end
       if  i~=a 
           disp ('wrong!' );
       end
end

hope it will help you to learn MATLAB

while true
    a=5 ;
    disp(' ');
    i = input('choose a number   ');
    disp(' ');
    if i == a
    disp ('RR');
    else 
        disp ('wrong!' );
    end
    disp(' ');
    j = input(' Stop? (input: "y" - yes or "n" - no)  ','s');
    disp(' ');
    if strncmp(j,'yes',1)
        break
    end
end
