C++ :: Continue Statement In Nested Loop
Feb 9, 2014I was wondering how I could use a continue statement that continues in a nested loop. For example if I have
for (int i=0;i<amount;i++) {
for (int j=0;j<I[i];j++) {
for (int k=j+1;k<I[i];k++) {
if (P[i][j]+P[i][k]==C[i]) {
//What should be here?
}
}
}
}
If the condition is met then the most outer loop (in i) should continue to the next iteration.
If i simply fill in continue; in before the comment then it only continues the loop in k so that is not what I want.
C :: Y / N Option To Continue - Compiler Does Not Read It As A Loop
Jul 30, 2013I've been having problems with my loop that asks if the user wishes to continue or not. The required input should either be 'y' or 'Y', or 'n' or 'N'. Anything else should be counted as invalid, and repeat the prompt for input. The first few times I ran my program, the compiler does not read it as a loop. The next few times just won't work properly.
Here is the prompt:
Code:
void question() {
char option;
printf("
Do you want to continue? {Y|N) ");
scanf("%c", &option);
[Code] ......
As it is, it immediately runs the else option, but otherwise runs just fine. I suspect it could be because I have not specified a size for the option variable, but I try doing that, and the prompt relegates everything to the else.
(And also, here's the rest of the code. Basically, it just assigns a value to the letters of the word (a/A = 1, b/B = 2, etc.), adds these values, and determines if a word is prime or not based on the sum.)
Code:
#include <stdio.h>
#include <string.h>
#define size 30
int main() {
char letter, word[size], lower, upper, option;
int i, value, ans = 0, a, choice = 1;

Visual C++ :: Exiting Application During While Loop Operation
Jun 16, 2013I have a VC++ 6 dialog-based application. This application is intended for reading data from a USB device (this is a FTDI FT245R chip). I have a start button on the dialog. On clicking it, unsigned char data retrieved from the USB device is displayed on the dialog. The start button invokes a function which includes a while (1) loop inside which the USB device is read and the values displayed.
There are no break or continue statements inside the always operating while (1) loop. All this works fine. My problem is how do I exit the application as normally it would just run forever? I have put an exit button on the dialog with code added to call OnOK(). Normally this would nicely close the application but as I have an endless while loop in my application so this button doesn't seem to work. Nothing happens on clicking it and clicking it repeatedly just hangs the program.
C++ :: Iterating Over Either Row Or Column?
Jul 3, 2014Suppose I want to represent an apartment building in terms of floors and rooms with a single data object. Each floor has the same number of rooms at any given time. During the course of the program, I will need to change the number of floors occasionally and will need to change the number of rooms on each floor occasionally. (Don't worry about the building permits needed to do this.) Now, I also want to be able to iterate over either each floor (think "row") or each room (think "column"). For example, I might want to program the equivalent of "Johnson, go fix all the front doors on the 8th floor" or the equivalent of "Johnson, go fix all the front doors to room B on each floor". (Yeah, I know, for the latter I could iterate over each floor and then access room B but that doesn't feel as "clean" as being able to iterate over a separate room/column.)

C++ :: Iterating Through Struct Members?
Apr 4, 2013Suppose I have a struct with 20 members. I want to assign each of those structs with values. Instead of accesing by explicit convention, i.e.:
Code: struct.member1 = 1;
struct.member2 = 2;
...
...
...
struct.member20 = 6;
Is there any way to encapsulate it in a for loop and use an iterator variable to indicate the member? i.e.:
Code: for (int i = 0; i < 20; i++)
struct.i = i;
The above is pseudocode but Im sure you get what Im trying to do?
C :: Possible To Display Time Continuously
Feb 20, 2013I created a program to display time continuously so it auto updates every sec but the issue is i cant integrate the code in the main program because to make time update continuously it needs a loop a infinite loop so none of the rest program gets to work. My q is : is it possible to display time continuously and make the rest of program continue normally? like a multi thread program because i want to display time every sec in the bottom of program. By the way this is console app not gui

C++ :: How To Move A Ball Continuously In 2D Scrolling Game
Dec 29, 2013The situation is , I have a ball which should move on a flat horizontal surface which i have created in a display of 800 x 400 . Right now!I am able to make it move left or right in direction using key inputs at a fixed speed.
But I want to make it move horizontally at a constant velocity without using keys. Like in copter game.
It should be able to move automatically , towards the right side.
Increment x position by speed variable does the trick but When I used it with keys I used to limit the movement like.
ball.x += ball.speed;
if(ball.x > 750)
ball.x = 750; // because my screen width is 800.
[URL] .... < this video will show what I really want to do with the ball
If you saw the game video in the link i gave, the ball kept moving with constant velocity. But it never went out of bound. What is keeping it from not getting out of display screen. Instead! its moving continuously... but stays almost at the center of screen. How?
C# :: Unable To Continuously Read More Lines Of Text
Apr 23, 2014This code works, but not fully This code reads com ports, when a string is available, I check to see if it contains some keywords defined in array If it does, i print out the string itself.
The problem i am having is that it seems to stop processing the data at some point but I do know that there are more strings to be read. So, it does keep reading more lines of data

C++ :: Header File That Is Continuously Updating To Extract Certain Variables?
Mar 10, 2013I need to write a C++ program, that extracts certain variables, x y z, from a file that is continuously being updated x y z. These variables are going to be used to recalculate a new answer.
My question is to see if it is possible to have an include .h file that is always being updated so that I can extract these three variables from it, and always have the newest venison of each variable, so that the answer to the equation is always the newest updated. Should I use fopen or fwrite to do this.
C++ :: Calculate Number Of Days Between Dates - Program Continuously Runs
Mar 24, 2014I have an assignment to write a program that will calculate the number of days between two dates (including leap years). We have to read the data from a file and in my current input file I have:

5 2 2005 2 5 2009
1 15 1998 1 15 2001
for testing purposes. When I run the program the console runs continuously spouting out "The days between your two dates are 1097." Which would be the correct output for the last set of dates entered, but I need to find out where I've messed up in my main.

I am not asking you to write the code for me or anything because I want to learn by doing it myself but all I am asking for is some pointers to where I am messing up. My program is already finished for what she asked for but I am trying to do an extra credit where she wants us to have the user decide how big the gameboard is and how many mines to hide in it.

C++ :: How To Read / Edit CSV File And Continue From Last Login
May 5, 2014I am working on a program that will do several mathematical calculation and will store the data into a csv file.The one below is just a prototype version of this.In my program,I will store my csv file as (current-date).csv using time.
With this in mind,I want my program to first check does (current-date).csv already exists.If not,the program runs normally and output all the data into the csv file.
However if (current-date).csv already exists,I want my program to read and edit that particular csv file,by skipping part1 in my code(name,id N etc.) and start with prompting the user for numbers straight-away.
In other words, if (current-date).csv already exists,the user should continue outputting the numbers from where the user last left before last termination instead of outputting the name,date & etc into the csv file again.
Eg: if no=22, continue inputting values from no=23 till terminating the program again and storing the values correctly into the csv file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <locale>
#include <string>
#include <sstream>
#include <time.h>
using namespace std;
// Program to read date N store it as currentdate.csv
