+2  Q: 

can scanf be terminated on pressing some specific key other than enter

Hello,

I have a situation here

i am taking input from user

using scanf can I terminate the scanf as soon as user presses the # key

please enlighten me on this

+3  A: 

No, scanf() (or rather stdin, by default) is line-oriented so it needs to read a full line.

Look into ncurses or similar libraries for "raw" key-by-key input.
