I want to write a C++ program that uses a class to do some calculations.
I pass arguments to the program, some of which are used to set up class members. A class function will then perform the necessary calculations.
I am wondering how I should pass the arguments from the program to set the class members and then call the function performing the algorithm.
One way to do this is by parsing all the to the class (using a list consisting of a key and a value) and creating a class function
It checks all the keys and if the key matches some predefined strings, it will set the class member value.
I would like some opinions and alternative ways to do all this, outlining both advantages and disadvantages when using them, and which one might be good candidate for implementation.
Hi List,
Is it possible to pass one argument to a shell program
eg) there is a shell program abc which takes one arguments
abc one
Due to some reasons I pass
abc one two
Now one,two must be considered as "one" argument to the shell programs. Any suggestions,hints are welcome.

I have a shell script that is attempting to call a c program.
I call the c program with ./dictool
dictool accepts arguments at runtime. It works by prompting the user for various commands, acting on those commands, spitting out an output, and then prompting for more commands.

How would I write an 'if' statement to check for... (4 Replies)

tk_setclass
Tk_SetClass(3) Tk Library Procedures Tk_SetClass(3)__________________________________________________________________________________________________________________________________________________NAME
Tk_SetClass, Tk_Class - set or retrieve a window's class
SYNOPSIS
#include <tk.h>
Tk_SetClass(tkwin, class)
Tk_Uid
Tk_Class(tkwin)
ARGUMENTS
Tk_Window tkwin (in) Token for window.
char *class (in) New class name for window.
_________________________________________________________________DESCRIPTION
Tk_SetClass is called to associate a class with a particular window. The class string identifies the type of the window; all windows with
the same general class of behavior (button, menu, etc.) should have the same class. By convention all class names start with a capital
letter, and there exists a Tcl command with the same name as each class (except all in lower-case) which can be used to create and manipu-
late windows of that class. A window's class string is initialized to NULL when the window is created.
For main windows, Tk automatically propagates the name and class to the WM_CLASS property used by window managers. This happens either
when a main window is actually created (e.g. in Tk_MakeWindowExist), or when Tk_SetClass is called, whichever occurs later. If a main win-
dow has not been assigned a class then Tk will not set the WM_CLASS property for the window.
Tk_Class is a macro that returns the current value of tkwin's class. The value is returned as a Tk_Uid, which may be used just like a
string pointer but also has the properties of a unique identifier (see the manual entry for Tk_GetUid for details). If tkwin has not yet
been given a class, then Tk_Class will return NULL.
