Given N tasks (numbered 1-N) and a series of task restrictions (do task 3 before task 2) print out all possible task orderings.
Example input:
3
3 2
Explanation: there are 3 tasks and task 3 must be done before task 2 (each restriction will have its own line)
Example output:
1 3 2
3 1 2
3 2 1
Here is what I am trying to do. I am reading from a socket. On receipt of specific data from the socket I have to start some computation (takes more than 5s). But if there is another input from the socket when the computation is in progress I need to disregard the ongoing computation and start all afresh. I have not come across any method which could suspend the ongoing task in the same context. I have thought of running computation in a separate thread. But I feel there must be some other methods doing it in the same context which I am unaware of. And, is my understanding correct that process would take up the new task only after completing the previous computation (which I do not want).

1. The data provided by the user to enter the keyboard.
2. The display of the stored data.
3. edit the data.
Example of data: name surname age.
I Try like it,its let me input and save it but how to edit it or i am doing it bad?

I have been asked to create a program to overload a function which should accept and print first one integer and then two integers. Here is the code i have produced so far: [URL] ....

int f1(int a);
double f1(double a);

I am aware the code should work. my only concern is the error i receive on line 12. I am certain there should be a value in the bracket but i dont know what.

I am looking a good design pattern that takes a combination of a Observer Design Pattern and Command Design Pattern.
Observer Design Pattern:

Command Design Pattern: Used to create a task. "Different Types of Task" ....
I am checking out this simple piece of code:
private void button1_Click(object sender, EventArgs e) {
Stopwatch sw = Stopwatch.StartNew();
Task Task1 = Task.Factory.StartNew(() => {
Console.WriteLine("Task1 started in : "+ " "+sw.ElapsedMilliseconds);
Thread.Sleep(4000);
Console.WriteLine("Task1 finished in : " + " " + sw.ElapsedMilliseconds);
}
);
}
and the results are :
Task1 started in : 2 in milliseconds
Task1 finished in : 4015 in milliseconds.
The problem is, that if i count the time with an external device, just like the timer of my watch or my cellphone s,the total time is 4,8 or 4,9 seconds, which i wouldn t expect that to happen.
The first thing i ve thought, is that it takes the ThreadPool about 800msec or 1 sec to create the thread so as to execute this task, but even if it is so, shouldn t the stopwatch count the time precisely?So , why is there a deviation between an external timer and the stopwatch ?
The following code is an example of how task are created with micro cos III in c. I am trying to figure how to create similliar code in C++. My problem is how do I instantiate objects and how to use member functions to represent task. Within the create task routine the address of function is passed as argument. How do I do this in C++? Will I need more than one class? New to embedded C++.

My use case is this: I have a C# Console application. I would like to run it via the Windows Task Scheduler, and would like it to attempt to run until it succeeds. My problem is that I can't achieve this. How does the Windows Task Scheduler recognize that a program has failed? I tried returning 1 or 32 instead of 0 but that didn't work. One possibility is to have the rerun logic in the C# console application but it feels like there must be a better way.
View 6 Replies View RelatedBasically the question is to develop an application that allows: Create an application which stores information about people, along with a task list.
The user should be able to Store people's information
Name,
Age,
Telephone number,
Address
-Retrieve information by entering name
- Remove a person's record by entering their name
-Return records for all people, sorted according to an information type other than age
-Enter a task which needs doing, a priority entered for its urgency
-View highest priority task on the list
-User should be able to remove highest priority item on the list
How to develop this application on a console command line interface style or any other style.
I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size)
{
int temp;
int smallest;
int current;
int move;
}

put it wont print the numbers sorted when I use my print function, just the unsorted numbers.
is there a to use printf to print certain number of blank spaces, where the number is derived from the output of a function?
for(m=low; m<=high;m++)
{
printf("t=%2d %'f(m)-1's %3c", m, ' ',*);
}
This is suppose to output
t=-3 *
t=-2 *
t=-1

I found it incredible that I could not found any working example of simple printing text while I was looking on google.
Somewhere I read I should include (I am not sure if I remember the name right but code::blocks on Windows did not find the header)
Code: #include <stdiostream.h>
so I am trying
Code: #include <stdio.h> and cout << "test"; (error: cout undeclared)
or
Code: #include <stdio.h> and std::cout << "test"; also I tried print("test");
as noted somewhere on Answers. Did not work (error: undefined reference print).
Last try I even got most of links in French. So I hope you'll give me the correct answer. Edit: I found it. I used puts()
i am using turbo c++ my program is based on maths equations and my final answer is 918 or any 3 digit number only but i don't want 918 to print instead i want only 18 to print. this program gives different output for every different input so i can't just minus 900 from it and get 18. i just want that no matter what 3 digit number is the answer,i just get the 2nd and 3rd digits while printing it and not the first.
the final answer giving equation is:-
f=2914-1996
where f is my answer and its 918
but i want it to print as 18 not 918

I did write a print function which the user put a number and then it will print out till that number
the output is correct ,, but is code correct ? or it could be better somehow ?
write a function named print_out that print all the whole numbers from 1 to n. test the function by placing it in a program that passes a number n to print_out , where this number is entered from the keyboard . the print_out function should have type void; it does not return a value. the function can be called with a simple statement:
print_out(n);

I have a problem with how to print out all the numbers that the user enters the code looks like this so far:
Code:
#include <iostream>
using namespace std;
int main()
[Code] ....
I want the program to print out all the numbers that the user has entered after the program have said the higest and lowest number is ?. But I do not know how to do this I thought it could be something like this:
Code:
cout << input[0];
//or
cout << input[i];
/*
Because i is the number of how many enters of numbers the user can do*/ But that was totally wrong tried to do another "for loop" in the first for loop but that was meaningless because it can't change anything in the first "for loop".
