C/C++ :: Making A Timer Stay Accurate
May 9, 2014
So I've been trying to write a good update loop,
if (SDL_GetTicks() - startTime >= 1000) {
fps = loops;
startTime = SDL_GetTicks();
loops = 0;
[Code] ....
It's based off of deWitter's 4th game loop. [URL]....
However, there's one major flaw. If the update() function takes a long time to execute, the timer slows down, a "second" doesn't last 1000 milliseconds, and the fps counter spits out numbers like 100 and 120 when the limit should be 60. Is there a way to make a timer that always runs with constant speed no matter how long the update function takes?

I am writing a game that is 2 to 4 players. i am wondering how to ask how many players, and make the score stay with each player. it is a rip off of zombie dice, this is what i have so far the playerScore array is to hold the score for each player and the turn array is hold hold the values that they rolled that turn, i also dont know how to clear out the turn array when it goes to the next player.
#include <iostream>
#include <cstdlib>
#include <cmath>
#include <ctime>
using namespace std;
int main() {
int playerScore[4];

I'm working on a project that is supposed to create 3 processes. Process 1 should count from 1 to 100,000. Process 2 from 1 to 200,000. Process 3 from 1 to 300,000. I've written the basic code of it but my processes aren't printing out very accurate numbers.
Here's my code:
/*ass1*/
#include <stdio.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>
#include <stdlib.h>
#include <unistd.h>
/* change the key number */
#define SHMKEY ((key_t) 8450)
typedef struct

My program closes after the out even though i've used cin.get():
I want the program to stay open at least until you press enter, even after the whole output.
Code:
#include <iostream>#include <string>
int main()
{
std::cout << "Please enter your name";
std::string name;
std::cin>> name;
// build the message that we intend to write

I have a function that rotates a vector 90 degrees. Only problem is, i never get negative values. For some strange reason, no matter what i do, the value of x is positive. And even if the x is negative. Once i put it into direction (struct with 2 values x and y) it turns again to positive. Im using VSC++2013 ultimate. At first direction was SDL_Point, so i thought it was SDL problem, but now it seems its something else.
if (c == '-') {
int x = direction.y;
x *= -1;
int y = direction.x;
direction = { x, y };
}

Write a program that computes and displays the charges for a patient's hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient the following data should be entered:
-Number of Days spent in a Hospital
-The daily rate
-Charges for the hospital services(lab test, etc)
-Hospital medication charges
If the the patient was an out-patient the following data should be entered:
-Charges for Hospital services(lab test, etc)
-Hospital medication charges
The program should use two functions to calculate the total charges. One of the functions should accept arguments for the in patient data, while the other function accepts arguments for out-patient data. Both functions should return the total charges.
I dont know why but the result always gives me 0??? This is what I have.
#include<iostream>
using namespace std;
double in_patient(int Numdays, double dailyRate, double Charge_hospServices, double HospMed_Charge);
double out_patient(double Outcharge_Service, double OuthospMed_Charge);
int main() {
double dailyRate, Charge_hospServices,HospMed_Charge,Outcharge_Service,OuthospMed_Charge;

how to produce a period signal that lasts 0.100 ms that is 35% red and 65% green using a bi-colour LED and the timer module?
while(ReadTimer0() < (unsigned int)165)
Its using this: OpenTimer0(TIMER_INT_OFF & T0_SOURCE_INT & T0_16BIT & T0_PS_1_32);
So does that mean that the period signal is 165 * 32 * 4/32 = 660 = 66%? I really just need to know how to calculate the period signal to produce 35% red and 65% green..

I need to set a timer but still have the program processing info. I have looked into using sleep but when using this all processing stops to my knowledge. I tried to use the settimer method but was having some issues since I am not using a dialog based interface.

I have some value in process memory (not my process). I have address of this value and want to execute function or smth else on changing this value. I think to use timers but I think they are too slow - low resolution(I read smth from 10 to 50 ms) and uses CPU too much. Can you offer me some other solution with not very much cpu usage but with checking variable value nearly 1 to 5 ms.

I am trying to create a five second timer that allows a value to be entered in that span of time. However, if a value is not entered within the five seconds, the timer ends and a value will no longer be able to be entered. I am trying to create a math test that has a five second time limit for equations to be answered.

My game runs in a while loop, as you can see in the code below. I need a timer, which won't stop this loop or freeze it, but it will wait, until timer is over and executes code without interfering with the while or for loop.
Code:
Code:
#include <iostream>
#include <iomanip>
#include <windows.h>
#include <ctime>
using namespace std;
char *map[25][25];

In an assignment where they were asked to write a simple alarm that went off every 12 hours. This seemed mildly interesting so I gave it a go. The alarm actually goes off every minute (to have it go off every hour, or every 12, or some other interval more cogs, shafts and pinions would need to be added to the mechanism).
Code:
/* A simple "stopwatch" that prints an alarm message every minute.
*
* 2-Nov-2013
*
*/
#include <stdio.h>
#include <stdbool.h>
#include <time.h>

I have attached a circuit diagram below, which has been tested. Currently you have to manually push the switch to change the brightness of the bulbs. I want to program a chip to automate this.
Over 90 days the chip will output a high signal in replace of the switch every set period of time (say once every 1.5days). I can use any chip but the smaller the better!

I usually use codeblocks until my professor gave me a project in which it was mandatory to use turbo c++ so how can I create the timer effect in turbo???
E.g. if i want to print 1 2 3 4.... in a gap of 2 seconds how will I do it in turbo c++?

I want to add a count down timer to my testing software 1hr and 30min
Its a 32bit console application, I want the countdown timer outputted above each question on the right side, timer only needs to output the time left at the top of each question so a live outputted timer is not important.
Questions are not random generated.
Also how to output "out of time" if the timer reaches 0 and for the test to end, I think branching is involved not too sure.
I already have, std::srand( std::time(0) ) ; at the start of the test to randomly generate the answer order.
