[Gaurav sharma]

I want to know about "time bounded input in c language" ...
it means user has only few seconds which has define by developer
if user is not give input on this time next line should be compile.
but note this this funda or logic should be in c language.....

You can use sleep() command to implement that .

Or other way would be to use user defined signal handling

[sriramchandrk]

Use alarm command

try to find in stevens book or google it.

One easy way is to fork a child process that will generate a signal after a fixed time. This signal when captured can be used to skip the line.
