I need the following program in a bit of a jiffy:
Four small programs:
* Parent - pipes, forks and exec 3 other programs - needs to wait for each program to finish and report exit status
* Program one - prompt for input, reads in string, writes to stdout
* Program two - reads input of program one through its stdin, change all chars to uppercase, writes to stdout
* Program three - add row line to start of each line / string entered, write to stdout
If this could be quickly done it would be muchly appreciated
Needs to be written in C for a unix env.
