Using flock to stop looping first open brackets.
Now I will give you an example to see how the flag works.
Create a variable equal empty string or nothing in the variable.
Another variable such as name equal string.
Right.
And in a backslash.
And all right.
Now I will use the flat wire.
I is not equal quotation marks.
Q call and I equal input Prentice's name.
This means as long as variable is not equal.
Q Do the statement or the block of code that we did which is I equal input parentheses variable named
after that.
Try that on terminal
as you can see it says right on the name.
I will write anything now.
Just watch out.
Here the flag works when a pipe Q Because in the conditions say as long as the variable y is not equal.
Q Let the statements work OK.
That's it for now.
Thank you for watching.
