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 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 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);

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'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?
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").

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"));
}

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.

i am trying to make a simple log in system without the use of database or whatever it is called.
my only concern is this
cout<<"enter password:";

how would i be able to make the characters appear as **** rather than the actual character that i would type as i am typing my password in CIN? or is it even possible?

View 1 Replies View RelatedI'm building a simple system management console application. I've abstracted the console "Menu" and derived from it a "WelcomeMenu" class with public inheritance.
The problem is that when instantiating a Menu* object and assigning it a new WelcomeMenu...I'm still not able to use WelcomeMenu's "ShowWelcomeMessage() with the Menu* object. Instead, I get "error: Class 'Menu' has no member function call 'ShowWelcomeMessage().' Which is true, but I thought a pointer-to-Menu object should be able to use the public methods of derived classes without casting in this case. Code follows.

What I'm trying to accomplish is to ask the user what their floor plan is (in square feet), have them pick what kind of material they want and give them a general price.
Which is working out great so far, but I would also like to add a loop at the end that cycles back if they want to re-do the estimate with a different material selection and if not exit out the program.
I've been trying do while and if/else loops but i can't get them to work right.
#include <iostream>
#include <string>
using namespace std;
int main() {
string custName, selection;
int custNumber, floorSize, material, contactSystem;

That's basically what I've come up with so far minus all the erroneous attempts. Though as is I technically complete the assignment, I would like the extra credit from making the last part loop.
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.
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

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 have the following private part of a class defined as follows:
private:
struct stats {
double ISIsum;
int authorCount;
bool operator<(const stats &a) const { return ISIsum > a.ISIsum;}
} *stats_;
bool compareSortByISI(const stats &lhs, const stats &rhs);
};
This enables me to sort this struct by calling:
std::sort(stats_, stats_ + authors_->getMaximumAuthors());
My question is, what if I want to have the option to sort by authorCount or ISIsum at run time. Is there any way to do this?
I can't see how I can override operator< twice and decide which one to call at use time.
I have been reading up, and it seems that all I need to do to finish up the installation of a library is to add in the search path for the library upon compile time.
Of course, I also read that directly copying the lib files can work too, but that may result in the over-writing of necessary files...
I read a more thorough document on mingw's linking processes and discovered that I could create a folder, install the library in that folder, and add the folder as a search path for mingw (so, basically, all i have to do is install all my libraries under that folder).
Is there a way to access the router settings via c++? My friend wanted me to write something that would turn off wifi broadcasting on his router when pressing the button in the program. The only way I can think about is to connect to the router via .net framework and then use reverse engineering (on the router settings site) to find a way how to simulate change of option via POST or GET method.

i have 1 error in these function that i'm confused. imagine the newstring size is more big than the oldstring, how can change the string, but only change the oldstring and add what left?
see these:

the result must be:
hello hello world
how can i change the replace function for it?
