Chapter 12, Problem 12.31HW

Implement a version of the standard I/O fgets function, called tfgets, that times out and returns NULL if it does not receive an input line on standard input within 5 seconds. Your function should be implemented in a package called tfgets-proc.c using processes, signals, and nonlocal jumps. It should not use the Linux alarm function. Test your solution using the driver program in Figure 12.47.

Extend your shell with pipelining (mandatory for teams of 3 or 4) The command $ cmd1 | cmd2 | cmd3 connects the standard output of cmd1 to the standard input of cmd2, and again connects the standard output of cmd2 to the standard input of cmd3 using the pipeline operator '|'. You will need to use the pipe() system call. Your shell should be able to handle up to three commands chained together with the pipeline operator (i.e., your shell should support up to two pipes pipelined together). This portion of the project should only require implementing support for a pipeline of 2 pipes/3 commands (no working with redirection).    HOW TO DO THIS IN C PROGRAMMING PLS HELP
Implement the PrintMenu() function. PrintMenu() takes the playlist title as a parameter and outputs a menu of options to manipulate the playlist. Each option is represented by a single character. Build and output the menu within the function. If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to execute the menu until the user enters q to Quit. Ex: JAMZ PLAYLIST MENU a - Add song d - Remove song c - Change position of song s - Output songs by specific artist t - Output total time of playlist (in seconds) o - Output full playlist q - Quit Choose an option:
The Ministry of Vybsie_Culcha intends to implement a grant for singers in order to offset difficulties experienced in the pandemic. The grant is to be funded from a fixed pool of funds (so the first set of singers that exhaust the funds are the only ones that are able to receive the grant). You are contracted to write a program that models the expected payouts. In order to reduce the possibility of fraud however, the ministry has decided to implement a (controversial) strategy that requires entertainers to prove they are the song owners by recording it at a Studio, even if already released. The Ministry maintains a list of Studios, and code for the Ministry and Studio classes have already been fully implemented. The starting code also includes calls to a template of a Singer class that interacts with a Song class. Your task is to execute eight(8) tasks that complete the Singer and Song classes.   MARKING CRITERIA (PLEASE REVIEW BEFORE STARTING) Criterion Mark(s) Accessors and mutators…
