I don't understand why my Do While loop skips over the input the second time round?

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 : ");
scanf("%d",&n);
remain=n;
[Code] ....
I've recently completed a fully functional round robin algorithm for a class, however upon running a myriad of test cases I found where mine fails. I think it best to show with an example:
Process-Burst-Arrival
P1 1 0
P2 1 1
P3 1 4
P4 3 8
P5 5 20
Currently what happens is this, it runs perfectly from process 1 through process 3. However once it reaches process 4 it does the appropriate thing and adjusts my total processing time (q variable) to the arrival time of process 4. Great! But then, it rolls over to check the queue again and it's bringing in process 5, changing q to it's arrival time. Then it proceeds to swap them in and out due to them both now being in the queue and time quantums/slices running out.
My question is this: How/where do I put a lock on the while loop that runs the simulated scheduler (round robin in this instance) to not grab the next process when there's a time gap in between each process.
This specifically is the two lines that I can't seem to get working as they should:
if(arrival[i]>q)
q=arrival[i];

I am so close to finishing this program of games, but I'm running into some issues while debugging it.
I've attached the google drive folder since there are several files (ignore the ones with [conflict], etc)...
First, I have the main menu using a switch to select the game. The default was set to exit. If initially when immediately opening the program you put in for say, a letter, it would exit like its supposed to. But if you went and played any of the games ], went back to the main screen, and entered a letter then, it would crash. I've put in a testing line to make sure that you enter a number, and not anything else.
Now however, if you play a game and then want to go back to the main menu, it will simply skip over waiting for your response and close the program. The same thing happens in the slot machine, I want to have it spin the slot machine by pressing enter, but it simply skips over the input, and I'm not sure why.

I just recently finished up a program that implements Dijkstra's Algorithm and I thought I would make a nice little menu for the user.
so the user can input their locations, I use Getline just in case their location contains spaces. However, when the user selects 2, It skips over the first input for the "Source" location and only lets the user input for the "Destination".
Any reason why this would happen? Am I missing something with Getline? Anyway, here's the code...
template <typename V, typename E>
void Graph<V, E>::Driver() {
bool done = false;
int menu(0);
InputFile();

I 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?
how I would easily round a double or a float to the nearest cent. It was easy enough to do it in visual basic or java, But i cannot figure out how to do it in C.
View 6 Replies View RelatedI am trying to make this while loop cut out / self break after 3 seconds. It is part of a simple game I am creating that gives the users 3 seconds to react otherwise it moves on to the next part.
while(1) {
key=getch();
if(key=='a'||key=='k'||key=='g') {
break;
}
}
All I need is it to end after 3 seconds, the rest of the code is working fine.
This sort of thing:
long startTime = System.currentTimeMillis(); //fetch starting time
while(false||(System.currentTimeMillis()-startTime)<10000)
If it IS for C, then I implemented it wrong or something.
it skips the input phase,, instead of inputting the last name it goes directly to the firstname then middle initail and street name are working fine but it skips the street name then goes to city and so on....

I am altering this program to include some alterations for a class. When I run it with start without debugging, it just skips to press any key to continue. It will not display the cout << "Volume of box1 = " <<boxVolume1.
#include "stdafx.h"
#include <iostream>
using std::cout;
using std::endl;
class CBox {
public:
double m_Length;
double m_Width;

Consider:
Code: template<unsigned int N>
class Test
{
private:

I just cannot understand why (clearly, we are calling <0, 0>, not <0, 8>). If I replace "N" with 8, it works as expected (at least for the beginning of the loop). I only tested on MSVC.
one of my project involves loop inside loops and creating random numbers. Here is what I have so far:#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
[Code]....
so the program will create a random value for the inflow. The idea is that the internal for loop will continue to run until the fill_level of the reservoir, which starts at 0, hits the capacity. The process of simulating how many years (each iteration of the internal for loop representing a year) is to be repeated 10 times by the parent for loop of the water_level simulation for loop.
The problem is that the random number that is supposed to created are the same number. THey are different every time I run it, but they are the same every time the loops repeat to make a new simulation.
We were discussing how to find average time complexity of different algorithms. Suppose I've a the following nested loop
for(int i=0;i<n;i++)
{
min = i;
[Code].....
Now the outer loop will iterate N times. the inner loop will always iterate 3 times no matter what the value of N is. so the worst case time complexity should be O(n^2) but what about the average case and the best case? I mean in terms of searching we can figure out and distinguish between the worst,best and average as it depends upon the number of comparisons. But here how can the average and best case be different then the worst case.
Alright, so to better myself with network logic I've decided to make a small net game.
I need to input commands to the console as well as output status updates at the same time. I'd prefer to write a gui interface for that, but I'd rather work with WinAPI as little as possible (I mean, look at the way it's designed...).
I'd like to do this with standard operations, limiting dependencies is a must for me.
how can i make a program which allows a user to enter an input for a time interval for example i ask a question and sets the input to be entered within 10 seconds...
View 4 Replies View RelatedI am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time
{
short year;
short month;
short day;
short hour;
short min;
};
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.
I have a float values I'd like to round off to the nearest integer value.
That is to say, if the float value is 44.234533, the integer value should be 44. If the float value is 44.682101, the integer value should be 45.
How do I do this?
To one decimal place?
Code:
#include <stdio.h>
int main() {
double num, trunc, round;
printf("
Enter a Decimal:
}
[code]...
That's my code currently, I've gotten it to round as I want, but I want it to truncate to one decimal place as well.If i enter 4.157, It should truncate to 4.1, and round to 4.2.
I have to write a program for class in which users will be inputting:
start time = startTime
number of minutes = callDuration
so first off, teacher wants us to input time as a floating point number such as 09.00
How do I validate the time so that users cant input i.e. 09.61 for every hour? In other words, so the user cant input minutes 60-99 for every hour.
then, when calculating:
endTime = startTime + callDuration
how would I make endTime display a correct time in such a situation: endTime = 09.45 + 00.30
so that it displays 10.15 not 09.75
The problem says: Draw a box with rounded corners. Define a class Box, consisting of four lines and four arcs. So I wrote the below code for that exercise:
#include <Simple_window.h>
Simple_window win(Point(100,100), 600,400, "semi-ellipse");
struct Box: Shape{
Box(Point p, int ww, int hh): w(ww), h(hh)
{ add(Point(p.x-ww,p.y-hh)); }

When I ran it I faced this exception:
Unhandled exception at 0x757FE9D7 (ole32.dll) in test.exe: 0xC0000005: Access violation reading location 0x00000004.
I know this refers to declaring "Simple_window win(Point(100,100), 600,400, "semi-ellipse");" in global state. But I did that because I had to do it. The problem is that how to attach lines and also object (here b) to Simple_window win in either parts (main() function and also Box struct).
I am making a game of quiz and i want to play a small clip in one of the rounds, but i dont know how to do it in c++ ....
View 3 Replies View RelatedThis is an example from C++ Primer on while loops shortened for simplicity:
int main() {
int value = 0;
while(cin >> value) cout << value;
return 0;
}
When I compile and run the above code the program keeps asking for input after I input nothing but pressing ENTER no matter how many times. The only way I can get it to stop asking for input is to input something other than an int such as a char or string. Program executes as intended after that. I have googled this issue and read all seemingly relevant results and nothing seems to pertain to my exact problem. I think it may have something to do with my computer's own settings or something and am baffled as to what it may be.
// PROBLEM - Use INPUT VALIDATION so number entered is positive. I can't get it to work
#include <iostream>
#include <iomanip>
using namespace std;
int main(int argc, const char * argv[]) {
// SUM OF NUMBERS
// Enter a positive integer
[Code] ....
I have a small loop that gets the user input, as well as acts as input validation to make sure he or she doesn't enter a value that is not within the specified range.
The user is supposed to enter a month number. E.g. if he or she chooses February, then enter 2, or December, 12.
It works correctly if they type a number that is not in the range, but goes into an infinite loop if, say, they type a string such as "month".
Code:
int main() {
// Variable Declaration(s)/Initialization(s)
int month=0;
// Get input
cout<<"Enter a month";
cin>>month;

How could I go about revising this?
I'm not finished with this code, but I am stuck on this one glitch. This is what I have so far, and it's not working.
Code:
int main() {
/*Please input an n value greater than zero. Otherwise, exit the program by entering a carriage return*/
printf("Please input an n value greater than zero. Otherwise, exit the program by entering a carriage return
");
int summation = 0, x, y;
scanf("%d", y);
for (y == x; summation <= M_E && x <= 34; x++)
