C++ :: Structure To Store Data From Database - Dynamic Initialization Of Variable
Jan 5, 2013I created a class (let call it X) which contains the structure to store the data from my data base. Them I have a class (call Y) which will contain a list for each row in my data base. Third, I have a class with thousands variables (Z). What I am trying to do is to take the list of objects (Y) that contains the data to initialize Z. What I want to now if I can do something like that.
Imaging that one of my rows contain the following data:
Type Nameofvariable etc...
"static const double; MNFAIL ; 0; 0; 0,25"
In my list I have a node with contain this data
I want to use the field Nameofvariable to initialize the variable called MNFAIL contained in my class Z.
Is it possible in C++
C/C++ :: Yes Or No To Restart A Program Or End It
Aug 8, 2014I just started learning c++ and got a problem now, i need a Y/N code, i case of yes the loop will restart and i case of no the program will end, Heres the code i got so far from trying to make my first steps.
#include <stdio.h>
void main() {
int a,b,c;
printf ("Zahl 1 Eingeben
");
scanf ("%i",&a);
[Code] ....
As u can see the other printf tasks are in german, but they are not important, the last one needs a Y/N "switch" y to restart the loop, and n to stop the program.
C :: Use A Loop To Restart A Program
Feb 21, 2015I've just started to learn C programming. In following program I need to use a loop, so at the end, it asks the user that if wants to try other numbers or not. If yes program restarts from beginning.
Code:

C++ :: Game Loop Design - Restart Round?
Sep 30, 2013I have a simple game loop.
while(true) {
//round initialization stuff
while(true) {
//capture input, make pieces move,
}
}
I am faced with the decision of what is the best way of restarting the game. The problem is, the condition for restarting a game is very, very deep inside the game's logic. So returning returning... is not an option, or at least, it ain't gonna be pretty.
So one of my considerations is to use a goto label, like so:
while(true) {
//round initialization stuff
while(true) {
//capture input, make pieces move,
} restart_round:
}
This seems to be the cleanest solution, since it allows me to fully reset the 'state' of the round, by first having all the destructors(pertaining to the round's objects) called, and then the constructors and other initialisation stuff.
Are there any subtleties that I am missing regarding this solution?

C++ :: Store A Reference Variable As Member Variable Of Interface Object
May 1, 2013I am having trouble compiling my interface. I am trying to store a reference variable as a member variable of the interface object. Compiler says that the variable has not be initiated correctly.
LCD inherits from VisualInterface which is expecting a DisplayDriver object to be passed in (DisplayDriver is another interface, but thats not important).
I pass the displayDriver object in when LCD is instantiated in maininterfaces.zip
I was pasing it before as a pointer but was told that this could cause me problems with memory leaks and a reference was better, but now I cant seem to get it to compile.
C++ :: Storing Variable Size Pointers Array As Class Variable
Mar 2, 2013This problem is best explained by looking at its output below. I stored 15 different values but when retrieved some are wrong.

public:
int ** pointer;

I need to store and retrieve the 15 different values correctly. How to solve this? The main thing is, I need to store the pointer in class A objects.
C++ :: Write A Loop Assigning Variable X To All Positions Of String Variable
Sep 8, 2013I have to write a loop assigning a variable x to all positions of a string variable and I'm stuck. I don't have extensive experience with arrays and I'm also a bit confused about C-String. The problem is below.
"Given the following declaration and initialization of the string variable, write a loop to assign 'X' to all positions of this string variable, keeping the length the same.
char our_string[15] = "Hi there!";
(Please note this is a 'C-string', not C++ standard string.)"
C :: Transform Local Variable Into Global Variable?
Oct 25, 2014I need to transform a local variable into a global variable so I can use it in one of my functions. I thought about passing the value as a parameter to this function but I can do this since the function is called inside the while loop and this variable counts how many times the while loop does (so the final value is outside the loop). Example to visualize better:
Code:
while(condition) {
function(parameter1, parameter2);
count = count + 1;
}
printf("%d
", count);
So, I need to transform the final value of "count" into a global variable. Can I do this?
C++ :: Store Function To A Variable And Call It Using That Variable?
Oct 15, 2013I want to store few different functions to a variable for different structs/classes and then call it later using that variable, is it possible? something like

int ID;
int special; // for function
};
item Key;
Key.special = UseKey(KEY_KING);
// now when I want to call function "UseKey(KEY_KING)" I want to use "Key.special", like this
if(iCurrRoom == ROOM_KING)
Key.special;
else if(iCurrRoom == ROOM_DRAGON)
Fireball.special;
C/C++ :: Assign One Variable Address To Another Variable

I thought it was ok to assign a variable address to another variable. Line 18 is where I get the error.

Feb 28, 2013I'm trying to make a database that stores the information without overwrite it. I want this program to store the client’s selection in somewhere that doesn't change and also that creates a new storage for the new value any time the client enters a new selection instead of overwriting it. I did something like that in my code but any time the program runs again and the client enters a new selection, the client’s selection is overwritten with the new value. I don’t know if it’s possible to do that (store the client’s selection in somewhere where doesn't change) with C++. I've been reading and I think I can create a database for my program.
