How can I loop an if statement

Im designing a game of battleship and I have the following code to prevent ships from overlapping.
x=zeros(1,36);
startingGrid=input('...')
orientation('..')
if orientation=='h'
while x(3)==1
startingGrid=input('... ');
orientation = input('... ');
end
elseif orientation=='v'
while x(4)==1
startingGrid=input('... ');
orientation = input('... ');
end
end
Now this works fine but whenever I enter one of the letters so for example 'h' (and it overlaps) then try again and enter 'v' it then continues with the program even if it overlaps so how can I make it work every time.

Your while loop does not update the variable you are testing to see if the loop should continue.

It is my understanding that in your scenario, you want the entire checking loop to restart if orientation is "h" but there is an overlap. I also understand that you don't face this issue with orientation "v" as it comes later in the lines and in the next loop iteration it again checks from "h".
For such a scenario, you can use the "continue" keyword in loop to go through the entire checking process again rather than heading to the next orientation. Kindly refer to the following pseudocode:
while (loop)
take inputs
if orientation=='h'
if overlap happens
continue;
end
end
if orientation=='v'
if overlap happens
continue;
end
end
end
Hope it helps!
