C++ :: Menu Program Broken Down Into Series Of Calls To Function For Each Of Menu Items
Aug 19, 2013
I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
I'm using winforms and I want to set a checkbox on a dropdown menu item, but I don't know how to access the dropdown menu items.
I know ToolStripMenuItem items are attached to ContextMenuStrip items but I'm not sure how to navigate into the ToolStripMenuItem section to read/set those menu items.
ToolStripMenuItem listbox_font_size; cmsListBox = new ContextMenuStrip(); cmsListBox.Items.Clear();
My project is to make a options menu for the user to select a shape and than draw out the shape. That whole process is already done and ready to go. What i am having trouble on is totaling the number of selected shapes. For example, at the end of the program i need to prompt a message saying ("You have selected "shape" this many times "number").
Can not seem to get the program to perform the calculations within the cases. Also, how do you set up the a prime function program within the menu. Have been trying for five days now.
This is what I have so far, it gives me a nice menu to select from and it all works but after I make a selection it closes the program. I tried to return to it but it won't work for me
#include <stdio.h> int main() { int choice; int deposit; int balance = 500; { printf(" CHOOSE FROM THE FOLLOWING
I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
I hate vague errors where I don't even know where to start looking for an error. Error happens immediately and it says "Unhandled exception at 0x5981c9c7 (msvcr100d.dll) in experiment.exe: 0xC0000005: Access violation reading location 0xabababab."
I just started learning the basics of programming. While encountering one of the practice problems in the book by Alex Allain I got a little confused. The question is as follows:
Write a menu program that lets the user select from a list of options, and if the input is not one of the options, reprint the list.
The author assumes you can answer this question only using if statements and/or loops (while, for and do).
This is the code I've written thus far:
Code: #include <iostream> using namespace std; int main() { int option; char reset;
[Code] ....
For some reason, the nested while loop keeps repeating even when you input a valid option (1, 2 or 3). I can't seem to figure out why this happens.
But I still do not load the excel file into my program by selecting the program from ContextMenu (right click on excel file and choose program). Although if select the path to excel file from the program, the data from excel file is loaded into the program.
I'm still missing something at function OpenExcelFileWithEasyForm(). How to complete this function to load the excel file into my program when selecting programs in ContextMenu.
I am having problems with setting up a menu as a function. The point of the menu is to display a list of 4 options and the user is supposed to choose one option and then the program will run. I am having trouble understanding how to display the menu once I run it because it is not working.
#include <iostream> using namespace std; int menu(int ans); // function declaration for menu void draw_triangle(int size, char ch); //function declaration for triangle void draw_downtri( int size, char ch); // function declaration for upside-down triangle void draw_diamond(int size, char ch); //function declaration for diamond
I decided to create a simple program to display a menu with options, while that is easy enough I had some difficulty when selecting an option that has options inside which also has an option again. While I had many issues in the past I'm finally finished with it and it works fine, but being new to programming and not knowing various other methods available.

I just started learning C and trying to create a program in C that will have a starting menu for a calculator. The problem is that I could do that with a switch/case but the assignment requires me to use if/else.
Here's what I have so far:
Code:
#include <stdio.h> int calc(); int menu(); int main() { printf("Hello. Welcome to the program. "); printf("Press RETURN key to continue...
[Code]...
How should I go from now using if/else to have those 4 choices?
I tried to write a menu program as a switch-case structure with a separate function for a switch-case structure itself. The outcome for it currently is an undesired one
Code:
#include <iostream> using namespace std; int menu(int answer); int main()
[Code].....
The output I get is one where it's just an infinite loop of "Bad choice! Please try again later.".
I'm trying to write a program that has a menu with a switch statement. I'm getting "case label'1' not within a switch statement" and subsequent errors for the other two choices and the default.
int main(){ int choice; Matrix A,B,C; cout <<"What would you like to do? "<< endl;
I just recently finished up a program that implements Dijkstra's Algorithm and I thought I would make a nice little menu for the user.
so the user can input their locations, I use Getline just in case their location contains spaces. However, when the user selects 2, It skips over the first input for the "Source" location and only lets the user input for the "Destination".
Any reason why this would happen? Am I missing something with Getline? Anyway, here's the code...
The program is not showing my full menu just the 0 Exit and the last line of text. This is the full main source file (not implementation file or header file).
I'm working on what I thought was a pretty simple program. I'm writing a menu driven program that will allow users to obtain specified measurements of several geometric figures. I was trying to test each each time I add a function.
I keep getting this error. error C3861: 'AreaOfSquare': identifier not found.
#include <iostream> #include <string> #include <iomanip> #include <fstream> #include <cmath> using namespace std; int menu() { int choice;
I've read that we can write a program that displays a menu of commands for the user to choose from.We can write some functions that implement these commands, then store pointers to the functions in the array :
We can get a similar effect with a switch statement but using an array of function pointers gives us more flexibility since the elements of the array can be changed as the programm is running.
I decided to write an example about this in order to understand better the context, I am facing some problems though :
Code: TEST2.c:9: warning: initialization from incompatible pointer type TEST2.c:9: warning: initialization from incompatible pointer type TEST2.c:25: error: too few arguments to function "*(arr + (long unsigned int)((long unsigned int)i * 8ul))"
The premise of this assignment is to create a menu driven, array of functions calculator. This is the code I have thus far (I haven't finished all of my comments yet, I've been to focused on clearing errors).
/*prototypes*/ void sum (int a, int b); void dif (int a, int b); void pro (int a, int b); void quo (int a, int b); void printMenu();
[Code] .....
I am using Visual Studio as a compiler, and I have the following errors:
error C2144: syntax error : 'int' should be preceded by ')' error C2660: 'sum' : function does not take 0 arguments error C2059: syntax error : ')' error C2144: syntax error : 'int' should be preceded by ')'
[Code] .....
I can only assume that I am making simple mistakes.
I need to be able to disable the items on a CCheckListBox but I can't change the code that calls AddString. I know I can use the CCheckListBox::Enable function to disable an item if I have an index but I don't have the index which would be provided by AddString.
I've tried intercepting the LB_ADDSTRING message and then looping through the items in the control but the string has not been added at this point so the last item in the list is never disabled.
I used Spy++ to see what messages were being sent and I noticed that LB_GETTEXT was sent so I tried intercepting this message (ugly hack) but this caused my app to hang - I assume because of the number of times the message is sent. Is there a way to disable the items?
I have to write a program that simulates a handheld gaming system. a system can have power toggled so its either on or off. when the system is on, its volume level can be raised or lowerd. a system has minimum volume level of zero and a maximum volume level of 10. a system stores games.
// simple game menu //simulates a handheld gaming system using namespace std; class Game { public: Game(int GameNumber = 3, int volume = 10);
