Wcd has been ported to different command-line shells: DOS, Windows cmd.exe and PowerShell, OS/2 cmd.exe, and Unix
NCD appeared first in The Norton Utilities, Release 4, for
Wcd was modeled after Norton Change Directory ( NCD ). Interactive directory tree browser with speed search. Wcd has a fast selection method in case of multiple matches and allows aliasing and banning of directories. One needs to type only a part of a directory name and wcd will No multiplication or division is needed to produce binary output to the screen.Overview Wcd is a command-line program to change directory fast. Printing binary must be done with shifting and bitwise operations. All user input must be completely qualified to meet the requirements above (up to 22-bit signed integer values). Use scanf() to read data from the user at runtime and overwrite the original values provided at execution time. The menu must also allow the user to re-enter a value for data and re-enter a value for the mask. If both values are within the range for signed 16 bit values, then the binary display should only show 16 bits. If data and mask are both within the range for signed 8 bit values, then the binary display should only show 8 bits. And they must be displayed such that one is above the other so that they may be visually compared bit by bit. Both data and mask should be displayed in binary format. The required operations are: Set, Clear and Toggle. The program should display a menu that allows the user to select different bit-wise operations to be performed on the data by the mask. This data field is to be is operated upon by a mask defined by the second argument. The first argument is to be considered a data field. The input must be fully qualified, and the user should be notified of any value out of range for a 22-bit signed integer.
You may assume the user enters only signed decimal numeric characters. Write a program that takes two command line arguments at the time the program is executed. The program will be tested with goc under Cygwin. Turn in just a single C source code file for the assignment. The second part of this homework is a program that should be written per the description below and turned in to the Canvas assignment for Homework #3.
