Program Plan Intro

Operator Overloading:

Operator overloading denotes a special case in which some operators like “=”, “+” or “==” are been treated as polymorphic functions.

The polymorphic function denotes the characteristic of applying a different meaning for anything in a different context.

Entities such as a function, an object or a variable are allowed to exist in more than one form.

Based on the argument types, the operators would have different behaviors.

For overloading an operator, a new meaning is been provided to user defined types.

Syntax:

return_type operator@(list_of_arguments)

{

//definitions

}

Points to be noted while operator overloading

All operators cannot be overloaded

New operators could not be created.

Precedence or associativity of operators could not be changed

Most of the operator overloading can be performed as either a non-member function or member function.

Operators are overloaded only when their usage is natural and unambiguous.

Whentheuserenters!!,themostrecentcommandinthehistoryisexecuted.In the example above, if the user entered the command: Osh> !! The ‘ls -l’ command should be executed and echoed on user’s screen. The command should also be placed in the history buffer as the next command. Whentheuserentersasingle!followedbyanintegerN,theNthcommandin the history is executed. In the example above, if the user entered the command: Osh> ! 3 The ‘ps’ command should be executed and echoed on the user’s screen. The command should also be placed in the history buffer as the next command. Error handling: The program should also manage basic error handling. For example, if there are no commands in the history, entering !! should result in a message “No commands in history.” Also, if there is no command corresponding to the number entered with the single !, the program should output "No such command in history."

2. UNIX Shell and History Feature [20 points] This question consists of designing a C program to serve as a shell interface that accepts user commands and then executes each command in a separate process. A shell interface gives the user a prompt, after which the next command is entered. The example below illustrates the prompt osh> and the user's next command: cat prog.c. The UNIX/Linux cat command displays the contents of the file prog.c on the terminal using the UNIX/Linux cat command and your program needs to do the same. osh> cat prog.c The above can be achieved by running your shell interface as a parent process. Every time a command is entered, you create a child process by using fork(), which then executes the user's command using one of the system calls in the exec() family (as described in Chapter 3). A C program that provides the general operations of a command-line shell can be seen below. #include #include #define MAX LINE 80 /* The maximum length command */ { int…
