Before looking at the CPP, knocked over some code, but always feel that learning is not enough system, the problem behind the book is more boring, do not want to write. C is very helpful in learning data structures and understanding the underlying.
Then came to Mooc to learn C language, watching the video although very tedious, but some things I did not notice before.
The first chapter is about the expressions and variables of C.
There's an interesting question about 0. The 0 inside the programming language is a horizontal bar in the circle, so that it is inherited in order to differentiate the letters in the Telegraph.
There is also about scanf and printf, why there is f behind, not in Python, because F represents format formatting. There is a scanf inside the thing is you want to enter something, enter what must write well, do not add things, scanf ("%d%d"); Is prompted to enter two characters, must have a space in the middle.
