P.s. I can use static in function and complete the code. Just checking for other alternative as static solution was ok but more option was asked

Answer 1

Besides global or static you could write it to some permanent storage such as a disk file or Windows registry.

And then there is my other trick of writing to other stack frames 😋

Thanks Brian

Answer 3

Ketan Lalcheta I hoped to see more responses with ideas for you. Here are a couple more that I thought of:

- Store the counter in a temp table of an in-memory db using SQLite.

- Store the counter in an environment variable. Here is an implementation:

I even made sure the code would be portable.

Answer 4

Ketan Lalcheta you could declare a static local variable within myCycle().

That would preserve the integer value between successive calls, but is not a global variable declared outside the function.
