I agree Haroon Ali because I didnt understand the way they explained in the other pages thinking that someone would post which would be easier to understand. But in turn I just got the links which even I could check myself....😑😑
Didnt intend for the comment to be mean. Its much faster to just google questions as most of which you have will be answered on Stackoverflow or have a wikipedia article. I also do not understand why you are so mad as I did gave you resources that explain what "\0" is.
