Redirecting input and output streams

Question

I just started on SPOJ. It tests by redirecting standard input and output to files. Is there a way to do that directly from the terminal instead of modifying the program.

If your on linux you can use the '<' operator. As in ./app < fileName it gets the input from the file instead of direct terminal.

So after compiling should i use ./a.out < filename ?
What about output?

If you want to redirect the output from terminal you use the '>' operator to a file. As in ./app < inputFile > outputFile
