C :: Program Based On Menu System - Option To Go Back To A Previous Menu
Apr 7, 2014
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?

Here is a simplified version of my Menu class, where submenus can be inserted arbitrarily deep. I need to add a new functionality "go back to previous menu", which I would like to be activated by entering 0 (universal command for all Menu instances). I considered the Memento Pattern, but that doesn't seem to quite fit. add that functionality to my Menu class.
#include <iostream>
#include <cstring>
using namespace std;
const int END = -1, NO_SUBMENU = 0;

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 have a menu for a project that takes a string input and does whatever option you specify. It works perfectly EXCEPT when it goes through the while-loop (while you didn't say quit the menu reloads). It will spew out all the text in the menu like a bulimic teenager. Then it reloads properly and asks you for an input like nothing happened. While this is not a fatal error (code still functions)...
Code:
#include <stdio.h>
#include <math.h>
#include <string.h>
double aa=0, ab=0, ac=0, sa=0, sb=0, sc=0;
char a1[13], o1[]="AAS

I need a program that has a login system and then a menu that has 3 options: Add, delete and exit. If I choose Add it wil ask for certain data of 5 students.
Then after registering the 5 students, another menu with the options: Search, Delete and exit. In search it will ask for an ID and then prints all the data of a single student. Delete gives me the option to delete the data of any user I choose.

I wish to add the item 'Website' to an MFC Dialog app System Menu so that it can activate the following method:
Code:
void CMyDlg::OnWebpage()
{
ShellExecute( NULL, NULL, _T("[URL]..."), NULL, NULL, 0 );
}// OnWebpage()
I have tried this:
Code:
#define IDM_WEBSITE (WM_USER + 101)
//..
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
pSysMenu->AppendMenuW(MF_STRING, IDM_WEBSITE, _T("Website"));
}
[Code]...
The code compiles without error but and the 'website' item appears on the System Menu but it doesnt do anything.
I've inspected the following but don't really understand how it works and it seems to me there should be a simpler way to accomplish my end.

Write an interactive text based menu interface (using a loop) that will allow the user to
Enter a task or assignment Display all of the tasks that are in the file Find a task by Course Quit For each task, you need to keep track of:
Course Name that it is for (e.g., CS162)
Description of the assignment (e.g., Finish Lab 2)
Due date (e.g., 9/26/2009)
Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("tasks.txt") into memory. When user enters the three items of a task, the program needs to read them in, save them in memory and eventually write them to the external data file ("tasks.txt"). The file format could look like: (The ';' is used as a delimiter or field seperator.)
Some Implementation Requirements:
Write at least four functions WITH arguments for this assignment. Use struct named Task to model task Use array of structs to model the collection of tasks. Hint: In this assignment, the description and course name may have multiple words in it. Therefore, you now SHOULD read using the 3 argument version of get. Watch out. When using the 3 argument version of get you need to make sure to remove the delimiter or newline. Therefore, anytime you read (even a confirmation message), make sure to eat the newline! Make sure to have a delimiter written between each item in the file – like a newline. This will be important when you read the information back from the file.
This is my code so far:
#include <iostream>
int main()
{
char cname[25],desc[20];

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?

void CDummyView::OnUpdateMenuItem1(CCmdUI* pCmdUI)
{

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.

To add my program into the context menu (when the user right click on excel file). I used the following code:
Code:
public static bool AddContextMenuItem(string Extension, string MenuName, string MenuDescription, string MenuCommand)
{
bool ret = false;
RegistryKey rkey = Registry.ClassesRoot.OpenSubKey(Extension);
if (rkey != null)
{
string extstring = rkey.GetValue("").ToString();
[Code] .....
I used the following function to retrieve the excel file path has been rightclick choose to load the program:
Code:
public static void OpenExcelFileWithEasyForm(string filePath)
{
try
{
string excelFilePath = Path.Combine(Path.GetDirectoryName(filePath), string.Format("{0} (EasyForm){1}", Path.GetFileNameWithoutExtension(filePath), Path.GetExtension(filePath)));
[Code] .....
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.

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.
#include <iostream>
#include <cmath>
#include <cstdlib>
using namespace std;
void showChoices();
double prime(double, double);
double abs(double, double);
double pow(double, double);

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 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...
template <typename V, typename E>
void Graph<V, E>::Driver() {
bool done = false;
int menu(0);
InputFile();

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.

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 :
Code:
void ( *file_cmd[])(void) = { new_cmd , open_cmd }; // 2 cmd's for simplicity
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:
#include<stdio.h>
#include<stdlib.h>
typedef void (*p_foo) (int);
void foo(int x);
void foo2(int y);
[Code] .....
The problems are :
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))"
