Write a program that creates three child processes and three pipes to communicate with each process. Each child process reads from different serial line (keyboard) and sends the characters read back to the parent process through a pipe. The parent process outputs all characters received on the console. A child terminates when two newline characters are received consecutively. The parent terminates after all three children have terminated. (hint: send-pipe and receive-pipe primitives can be used)

Embedded Software Development

Using specific programming languages (like C and C++) to write code for a specific hardware device in which it runs is called embedded software development. It makes the device smart by performing actions based on user's input which improves the user experience. They are designed to perform function-specific tasks rather than doing multiple tasks like computers. The embedded system is incredibly intuitive. An embedded software system could be a system developed and organized on any device, apart from an old-fashioned computer. It is the brain of a specific device; however, it is a solely useless tool and simple to elucidate what software system is embedded.
