I want to make 1000 lines program as a project so please give me any idea about it?

Answer 1

1000 lines is a huge project even in CPP.
I don't mean to discourage you, but based on your history of codes published on SoloLearn, I would start with something smaller first :)
Besides the number of lines can hardly be a measure of quality. Sometimes you can solve very difficult and complex problems with very few lines of code. Like there are many sololearners who are able to write complicated programs in a single line of code (oneliner) e.g. in python or ruby.

My suggestion is to pick a topic that you find interesting and challenging at the personal level, and make a project from it. If you find something that you can actually use or benefit from in your daily life, all the better, because it will give you motivation not to give up half way.

Happy coding!

Answer 3

I agree that you shouldn't go by length but by the degree the project challenges you.

It should feel a bit, but not too hard - solvable with experimenting and reading up a bit.

Try to make it SHORT instead of long - efficiency!

Better to write ten 100liners that challenged you somewhat than to write one 1000liner where half of it is print statements or other simple stuff.
