If you have a program Prog that reads from console (and by 'console' here you mean that it actually reads from the standard input, i.e. you use System.in in Java or scanf/cin/getline in C++ without explicit redirection 'magic') then you can make it read from a file simply by running it like that: $ Prog < task.in here '$' is just a prompt symbol - you shouldn't type it and '<' means redirecting the standard input to file 'task.in'. If you also want to save results to, say, task.out, then run it like: $ Prog < task.in > task.out
It works in any Linux shell I'm aware of and also in Windows command line interpreter. 2014-04-09 11:33 GMT+04:00 Moustafa F. Alzantot <[email protected]>: > what language are you using ??
