C++ :: Execute The Previous Statements After Else Statement?
Mar 10, 2013
I have a condition and I would like to instead change the condition so that it would execute the previous statements after else statement.
It seems hard to explain but I'll try my best to illustrate anyway
if (condition)
<statement1>
else
<statement2>
So I would like to change the condition so that
if (condition)
<statement2>
else
<statement1>
And the condition is
Code:
if(!lightStateAtNextLink || !bIsLightEnAtConnection && nLinkNext.IndexToAttachedNode() != pVeh->_.stAutopilot.m_dwNextNode || bIsLightEnAtConnection && nLinkNext.IndexToAttachedNode() == pVeh->_.stAutopilot.m_dwNextNode)
And I have changed that to this. Is this correct?
Code: if(lightStateAtNextLink && bIsLightEnAtConnection || nLinkNext.IndexToAttachedNode() == pVeh->_.stAutopilot.m_dwNextNode && !bIsLightEnAtConnection || nLinkNext.IndexToAttachedNode() != pVeh->_.stAutopilot.m_dwNextNode)

Im going through a C tutorial and im going to create a Database as part of the course. Im just in the very beginning of the project so its a very simple program so far.
Code:
#include<stdio.h>
main(){
/*Variabler for att lagra information om skiva*/
char title[200];
char artist[100];
int tracks;
int price;
[Code] ....
The first switch case statement takes me to the menu of choice, 1 or 2. However, chosing menu option one and trying to input a title or artist name, the program crashes.
Next, going into menu option 2 and then trying to print out, for example, title nothing happend. The process just ends.
Again, im sure this simple prototype is full of errors ....

when i uncomment statements in the following ,it works perfectly fine for infix to postfix conversion.although comments are simple cout statements,, execution with cout statements as comments breaks in b/w.I have found this particularly with a^b-c.DevCPP is also showing similar behavior. I can't understand what's going on.I am working on code blocks.
#include<iostream>
#include<cstdio>
#include<conio.h>
using namespace std;
char stk[15];

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;

Say a user installs and uses the software for awhile. Then they uninstall it. Client wants the database containing client data to remain behind, in case they ever re-install the software. Which is fine.
So then.. they re-install the software. Client wants them to have the choice to either use the existing database, or to create a new one. When the software fires up, it always checks for the database, and creates one if it's not there. So how can I determine if the instance is a new install, or a current install, given that the database will be there no matter what?

I am in the process of creating a game that has two players machine and person. The player is selected randomly each round. So if the player is selected, he needs to choose a number from 1-9. Then the machine needs to choose another new number either in the same row or colunm.(i figured out how to check against col.and row). Then keep going until someone reaches 31.
I'm stuck on how to add the numbers from previous rounds and have them reflect in the new rounds. While at the same time using the last entered number(last numbers) as a reference has to whether or not the new number is valid.
Ok I created a while loop as suggested. But it is not adding each round like it should. So the question is: What is wrong with the code after the while loop?
while ((x != 0) && (suma < Meta)){
cout << "SUM =" << x + last number << endl;
if (player == Person) {
x = machinerandomnDigit(last number);
sum = sum + x;
player = Person;
last number = x;

For my assignment I have to have an array with only zeros.
Code:
int a[20] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; Then I need to send it into a function that makes the array like this
Code: int a[20] = {0,1,2,3,4,5,6, ... , 19}
Which I have done here
Code:
int initialize(int a[], int n) {
int m = 0;
int i;
printf("
[Code] ....
Now I need to do the following with the array. I need to take whatever value is in each position and add that value to all of the previous values. like this.
Code:
a[3] = a[3] + a[2] + a[1] + a[0]
only for every a[i] I know that I can code this the long way, but I just can't see to be able to find out how to do this a better way.

//#include "stdafx.h"
#include<iostream>
#include<cmath>
using namespace std;
//class declaration
class dayType{
public: int presday;
[Code] ....
So everything works perfectly, well not everything lol. Code compiles successfully without any errors but previous day does not calculate. In a sense that when it asks for number of previous days it returns a blank statement.
For example: Previous number day is: shows nothing

Below is the sample of the code :
int summation = 0;
for (it= s.begin(); it!= s.end(); ++it) {
summation += std::atoi( ((*it).substr( 8 )).c_str() );
}
Nos after the first 8 characters are the ones I need to perform addition on.
do the summation of these nos.

I have started making a text adventure game.
if (Choice == 2) {
cout << "" << endl << "You follow the light to the end of the hallway, you find your self in a room" << endl
<< "with natural light coming from a hole in the ceiling." << endl << "" << endl << "You hear the door you just came through, slam behind you!" << endl << "" << endl
<< "There are three possible directions." << endl << "" << endl << "Do you:" << endl << "" << endl << "1) Go forward" << endl << "" << endl << "2) Go left" << endl
[Code] .....
Ignore the if (Choice == 2) at the beginning, that's linked to some previous code.
I want to make the player go back to the first bit of text but i'm not sure how to do this if they keep choosing to go back and forth from one location.
I first thought of doing it by just putting the text back in after they have chosen the option, but I can't do this infinite times.

My problem is that some of my conditions are not being triggered when the price level of a medium or large discount is smaller than the cost of the widget(defined as .40) An example being ,base price, $2 med discount 80%, and large discount 90%. My med discount is,1.6(80%) off of 2, so $.40, which is fine, but 90% off mean 1.8(90%) off of a base of $2, which is $.20 which is too low., and should trigger the 4th if statement, Nick you are discounting large purchases too much!. However when I run this in the program, I am triggering the first if statement.
#include <math.h>
#include <stdio.h>
#define widget_cost 0.40
int main (){
float sellprice;
float discount_med_price;

Is it possible to write a program such that it will automatically execute the function in queue base on their priority even if user programmed it randomly?
Code:
function1(){ very_important; }
function2(){ important; }
function3(){ less_important; }
int main() { // Programmed by user
function3;
function1;
function2;
//Output: Program will execute function1, 2 and lastly 3.
}

For easier debugging, I would like to execute an own (predefined) function while beeing in a breakpoint (e.g. print some variables to a file).
Does there exists such a feature?
e.g.
- run program to a breakpoint
- a) press a keyboard-function-key (which calls that predefined function)
- b) or hover with cursor over a variable (and modify somehow the routine which shows its content on the screen)?

i need to create an small windows form, with some buttons, and then those buttons will "exectute" an action on a remote webserver.
Im searching with http requestings and didn't find nothing useful for what i need.
The basic thing is that i just need to press "EXECUTE" and then c# will press one link in the Webserver. I do not need any feedback from the page. I just need that C# execute a link like localhost/startbackup.php then the actions from the startbackup.php will run.
I do not need any information regarding if the page was successful executed or not, or even if it opens one window. Nothing.

I'm wondering whether it's possible to implement MPI to execute a process in parallel from deep within a C++ solution.
I've created a solution on VS2005 that links to several static libraries, and within one of these libraries there is a set series of tasks that require execution many times - they're independent so I'd like them to execute them using MPI if possible to speed up the run time.
The pseudo-code is:
Code:
for(i = 0; i < n; i++) // n is number of times to execute process {
PerformTask(data[i]); // perform the tasks required for each iteration of process
}
So, instead of conducting the tasks within PerformTask() in series n times, I want to split the array data between multiple processes such that they can each be allocated an even proportion of data to perform the tasks on. Pretty textbook reason for wanting MPI, right?
Now, I've read up and understood the basics of MPI implementation, but all the examples I've seen are called within the main() function of the program. But I need to do all this from within a static library, is this possible?
I've made some early attempts at implementing this, but get an error indicating the process wasn't initialised: "Error encounted before initializing MPICH", which I assumed would be due to trying to make the MPI calls outside of the main() function.

I've just started learning the C language, and I'm stuck on something that is probably quite simple.how to get IF statements working within WHILE loops. My code is below. I am trying to write a program to count the number of words in a sentence, and obviously stop counting after a full stop has been entered. I created a variable called 'spaces' which will increase by one after the user enters a space. However, when the IF statement is in place, the loop never terminates, even if I enter a full stop. When I delete the IF statement, the loop functions correctly.
Code:
#include <stdio.h>
int main()
{
char x;
char a;
char y;
int spaces = 0;
}

PrintCharacterLineEnd();
This is a code. the string "letter3" contains the string "

However, as of right now it's not working.
