Summary
(a) We can pass parameters to a program at command line using the concept of ‘command line arguments’.
(b) The command line argument argv contains values passed to the program, whereas, argc contains number of arguments.
(c) We can use the standard file pointer stdin to take input from standard input device such as keyboard.
(d) We can use the standard file pointer stdout to send output to the standard output device such as a monitor.
(e) We can use the standard file pointers stdprn and stdaux to interact with printer and auxiliary devices respectively.
(f) Redirection allows a program to read from or write to files at command prompt.
(g) The operators < and > are called redirection operators.
