Hey there;
I've run into a problem!
I have a program that is supposed to do multiple things.
Therefore - I have a menu (switch statements).
Is there any way I can make it so when 1 statement finishes, it can go back to the main menu? I can add a case for X (10 we'll say) that will end the program.
If there isn't a way.. how should I do this menu?
use a while loop
bool done = false;
while( !done )
{
//show menu and execute switch statements or other stuff
}You can use other kinds of loops too, depending on what you want it to do.
int main()
{
// Declaration of integers
int index=0, intChoice=0, DatabaseSize=0;
bool finished=false, Flag=false;
// Declaration of the Array of Structs with size intIndex
User UserA[SIZE];
// Install the inStream and outStream
ifstream inStream;
ofstream outStream;
// CHECK TO SEE IF FILE WILL OPEN
inStream.open("MasterUserFile.txt");
if (inStream.fail())
{
cout << "Cannot open MasterUserFile.txt for reading, aborting" << endl;
system("PAUSE");
return 0;
}
while(!inStream.eof())
{
inStream >> UserA[index].user_id;
inStream >> UserA[index].firstName;
inStream >> UserA[index].lastName;
inStream >> UserA[index].password;
inStream >> UserA[index].priority;
index++;
}
// After the contents has been read in, it no longer needs to be open
inStream.close();
// Menu
cout << "INFR1100U final project: \n";
cout << "\n***********MENU**************\n";
cout << "_____________________________\n";
cout << "Add/Remove Options\n";
cout << "1. Add New User\n";
cout << "2. Remove an Existing User\n";
cout << "_____________________________\n";
cout << "Modify existing users\n";

cout << "4. Change Priority\n";

cout << "5. Print User Information\n";
cout << "6. Print All user Information\n";
cout << "_____________________________\n";
cout << "Misc. Options\n";
cout << "7.Write Records to Database\n";
cout << "8. ";
while (intChoice!=10)
{
cin >> intChoice;
switch(intChoice)
{
case 1:
// Prompt user
cout <<"\nAdd User\n";
while (!finished==true)
{
cout << "\nPlease enter a username: ";
cin >> UserA[index].user_id;
cout << "\nPlease enter the users first name: ";
cin >> UserA[index].firstName;
cout << "\nPlease enter the users last name: ";
cin >> UserA[index].lastName;
cout << "\nPlease enter the users password: ";
cin >> UserA[index].password;
// User priority check
while(!Flag)
{
cout << "\nPlease enter the users priority (1-7):";
cin>> UserA[index].priority;
if (UserA[index].priority <=7 && UserA[index].priority >=0)
{
Flag=true;
}
else
{
cout << "Error, please enter a number that equal to 0 and greater, less than 5 and equal to 5"<<endl;
}
}
// Add one to the array for the next time.
index++;
finished=true;
}
break;
case 2:
/*
// CHECK TO SEE IF FILE WILL OPEN
outStream.open("MasterUserFile.txt");
// Attempt to open to write.. if fail, shut down!
if (outStream.fail())
{
cout <<"Cannot open MasterUserFile.txt. Aborting";
outStream.close(); // Close 1st file if it fails
exit(1);
}
// Declare a temporary variable to save the search query and prompt user for action
char TempSearch;
cout <<"\nRemove User - Please enter the User Name (ex. 12345)";
cin >> TempSearch;
if (!strcmp(UserA[index].user_id, "TempSearch"))
{
cout << "";
}
// Close the file
outStream.close();
}
*/
break;
case 3:
break;
case 4:
break;
case 5:
break;
case 6:
break;
case 7:
break;
case 8:
break;
default: "GG you broke it.";
}
}
return 0;
}Still ends after I finish entering a user.
You didn't put the menu in a loop as I suggested earlier.
bool done = false;
while( !done )
{
// Menu
cout << "INFR1100U final project: \n";
cout << "\n***********MENU**************\n";
cout << "_____________________________\n";
cout << "Add/Remove Options\n";
cout << "1. Add New User\n";
cout << "2. Remove an Existing User\n";
// etc etc etc
}My trigger works the same way.. it still doesn't work. Is it because of the breaks?
you need to make a couple logic changes.
while(intChoice!=10)
{
cout << "INFR1100U final project: \n";
cout << "\n***********MENU**************\n";
cout << "_____________________________\n";
cout << "Add/Remove Options\n";

cout << "_____________________________\n";
cout << "Print information\n";
cout << "5. Print User Information\n";
cout << "6. Print All user Information\n";
cout << "_____________________________\n";
cout << "Misc. Options\n";
cout << "7.Write Records to Database\n";
cout << "8. ";

}Where?
Where what? All I did was change what you posted and moved that while statement to the top of the menu.
