I am currently developing a program, and I forgot how to print "%d", literally, so compiler does not recognize it as an integer, is that "'%d'"? ("%d" is just example so you can know what i mean").
It's actually a very simple program which I write in the console (visual basic 2013) for some system calls, hoping to be helpful to everyone, most of the code I wrote I just miss the above problem.
I will go try with " ' ' " and see if it works.
