Reading console output

I am writing a program that uses system() to pass commands to the command interpreter. Is there a way to read the output that the commands produce?

NAME
lpc - line printer control program SYNOPSIS
lpc [ command [ parameter(s) ] ] DESCRIPTION
lpc provides limited control over printer and class queues provided by CUPS. It can also be used to query the state of queues. If no command is specified on the command-line, lpc will display a prompt and accept commands from the standard input. COMMANDS
The lpc program accepts a subset of commands accepted by the Berkeley lpc program of the same name: exit Exits the command interpreter. help [command] Displays a short help message. quit Exits the command interpreter. status [queue] Displays the status of one or more printer or class queues. ? [command] Display a short help message. LIMITATIONS
Since lpc is geared towards the Berkeley printing system, it is impossible to use lpc to configure printer or class queues provided by CUPS. To configure printer or class queues you must use the lpadmin(8) command or another CUPS-compatible client with that functionality. COMPATIBILITY
The CUPS version of lpc does not implement all of the standard Berkeley commands. SEE ALSO
