I've written a tiny program in Ansi C on Windows first, and I compiled it on Ubuntu with the built-in GCC now.
The program is simple:
- read the line from console with
scanf(). - Analyze the string and calculate.
But something weird happens. When I try to move the cursor, it prints four characters:
- pressing Up prints "
^[[A" - pressing Dn prints "
^[[B" - pressing Rt prints "
^[[C" - pressing Lt prints "
^[[D"
How can this be avoided?
Why does it print these 4 characters instead of moving the cursor?
