C++ :: How To Make A Long Time Periods If / While Statement
Feb 8, 2014
I'm making a program that would run 24/7 and that could be run on multiple computers that are all running Windows (the program would be in the startup folder of the computer).
So I'm searching for 2 functions, one that would check if the program has been already launched on this computer and another one that would do a save every 24 hours. but for the second one I don't know what I should do because I think that a loop with sleep() would take too much power for the cpu

How can I read a file that contains numbers only, but read it by three digits at a time? I have a long string of numbers and every three digits corresponds to a particular number in itself. i.e. a string of 064045154 would need to be read as '064' '045' and '154'. I need to then subtract one from each of these numbers and the new values I need to convert into their ASCII characters and place these in a new file. This is what I have (focusing on the 'Decrypt' function) but all it does is in the new file place a string of the same character repeated over and over a total number of times equal to the number of integers in the numbers file.
Code:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
#include "limits.h"
int Encrypt(char * FILENAME)
[Code]..

I have a long long int k=0x0000888804eaad0e
And i need the reverse of this (nibble wise) in other long long int variable.
That is i want the result to be = q=0x0000e0daae408888;
Or the result also can be like this = q=0xe0daae4088880000;
How to accomplish the above?

The program i am trying to make is for practice of using switch. the idea is the user enters a number and the program will print a day of the week corresponding to said number.
the statement is not complete with all cases yet, but i dont want to write all of it until i am sure of it being correct.
errors when compiling (gcc) are as follows
1 warning and 3 errors generated.
Robins-MacBook-Air:array2 RDenton$ gcc array2.c
array2.c:26:9: warning: format string is not a string literal
(potentially insecure) [-Wformat-security]
printf(a[uservalue]);

I recently wrote a "Tic Tac Toe" console game, and i seem to have a problem in my winning conditions, as when it checks if the player won (should have won) it doesn't take the appropriate action.
The winning conditions are in CoreLogic.cpp
here's the code, might not be the most pretty and clean code ever but it works for me.
there are more files i just didn't feel the need to include them all since the problem is only within CoreLogic.cpp and possibly in main.cpp
pos1-pos9 have been declared in the UserInterface.cpp and are being used to determine the correct decision to do within CoreLogic.cpp
Nothing happens when you win at this point it just exits the program.

Say I want to leave a program running and it stops when I press F9 for instance, I'm looking for something like (and note this is just a generalization).
#include blah
using namespace std;
/wait 2 hours
/key.press = F9
return 0;

How do i make the srand() function make new numbers every time i call it? Now it seems like it repeats its result over an over again.
Below is a program that should generate random numbers for 3 dices and print these out. But it prints out the same nr over and over.
Code:
#include <stdio.h>
#define MAX 100
int filler(int dice1[MAX], int dice2[MAX], int dice3[MAX]) {
int throws, nr;
printf("Define the number of throws");
scanf("%d", &kast);

This is a round robin execution. with gantt chart. arrival time and burst time. I think there is an error in my formula to get the right answer,i cant resolve it but my program is running. What is the code or the right formula??
#include<stdio.h>
int main(){
int i,j=0,n,time,remain,flag=0,ts;
int sum_wait=0,sum_turnaround=0,at[10],bt[10],rt[10];
int ganttP[50],ganttStartTime[50];
printf("Enter no of Processes : ");

I've written a code that request for a password and its suppose to look like this.
Sample Output (inputs in bold)
Please enter a password: pass6
Passwords must be at least 7 characters long
Please enter a password: TarrantNW
Passwords must include a digit or dollar sign (0-9, $)
Please enter a password: Tccd-03
But when I run the program it stops at "Passwords must be at least 7 characters long" and the box closes and where I should put the loop=
#include <iostream>
#include <cstring>
#include <cctype>
using namespace std;
const int SIZE = 7;
char password[SIZE + 1];

I have a problem with converting a C++ string into a long double. In order to do this, I used the function strtold, but the result I get is only the integral part, that is: if for example the input string is 12.476, I only get 12 as the converted long double value. This happens with atof too.
Here is my code:
#include <stdio.h>
#include <stdlib.h>
#include <string>
#include <sstream>
string test = "12.345";
long double test_longd = strtold(test.c_str(),NULL);

Working on a Project Euler problem and the question asks for the largest prime number that is a factor of 600851475143. As you can see, this is significantly larger than the maximum of a long data type, which maxes out at 2147483647.
I'm running on Windows 32, so int64 is not a valid option for me. It seems like I'll likely have to use a different language to solve this problem.

So I have problem with my code, I'm trying to convert string to long and then string to double, but I get this when I compile it:
terminating with uncaught exception of type std::invalid_argument: stod: no conversion
I was thinking if there is a way to do this without using (stol) or (stod)
Market::Market(string filename)
{
string line, word, date, stockprice;
long realdate;

I am trying to highlight integers in a textbox.
The problem, is that I dont know how to make Regex get Integers no matter what (e.g. even if an =, >,<,>=,<= sign is in front or anything) unless it is encased in a string e.g. "'s or whatever.
My current code does this:
I do not want the numbers to be highlighted if they are in a string.

If I give any number as input, the output is always 0. why? where's the problem ? p

I have some codes which are not efficient enough to get the answer faster.
Q: Tom is looking for a car with high miles per gallon and high horse power.For example:P1--Toyota with MPG=51,HP=134, the P2--Honda with MPG=40,HP=110, P3--Ford Fusion with MPG=41,HP=191,P4--Nissan with MPG=35,HP=195,P5--Volkswagen with MPG=30,HP=140
Since,p2 is worse than p1(in terms of MPG,HP) and p5 worse than p4(MPG,HP), thus they are cancelled. The leftover 3 cars are considered interesting cars.Tom wish to find all interesting cars from the list but there's too many of them. Thus write a program to find this list as fast as possible.(C++)
int SimpleAlgo2 (int &n, int &d, vector< vector<float> > &point) {
vector<bool> isBest(n+10, true);
for (int i=0; i<n; i++) {
for (int j=0; j<n; j++) {
// We will check if point[i] is strictly worse than point[j]
// no need to check if we already know that point[i] is not the best
if (isBest[i]) {

I am trying to print out 2^1000. I am not entirely sure on how to implement the constructor. I currently just have x.push_back(n) as my constructors implementation. For the function double(), it is suppose print 2^10 as 1024 and the function addDigits() should print 2^10 as 7. Am I suppose to create a Long object with 2 as a parameter and then use double() to double it 10 times?

So I'm trying to learn how to use time for time based movement and what not. I did this only knowing the command time(&variable)
time_t timer;
int I, X;
void main() {
time(&timer);
X=timer;
while(I==5) {
[Code] ......
There's probably some other better way to do it... Obviously but for now I see it as putting current time in X.
start while
take in time constantly until I is 5
constantly asking is time>X(preset time 5 seconds ahead)
if it is
display message and add one to I
Why doesn't this display my message after 5 seconds?
