Hi, when i program some code, i find a terrible thing, which maybe is useful to u.
We should not give a variable with it type, like this, "char ch_***". Why not?
You can think that if your project is large, you will change a variable any type , which you will miss if it is the type you write. ha ha, you will be dizzy.
Okay, all that for you. Maybe useful to u.
