I'm trying to implement this queue class, and I don't know why it won't compile. I wrote a main function in the main.cpp file and even commented out the calls to functions add and removed and still gave me the fatal error.

I keep running into this error, even though the first few times i built and ran something it worked perfectly, and since I'm new to CodeBlocks (or any IDE/Compiler for that matter) what to do.Any code i put in, it'll give me this error....

I've been using VS2005 for many years without any problems. This morning I needed to rebuild a library called gdk-pixbuf which I've built many times before. It contains a source file called gdk-pixbuf-animation.c
If I build my Release version with Link Time Code Generation enabled I'm suddenly seeing the following error message:-
fatal error C1047: The object or library file '.Releaseobjgdk-pixbufgdk-pixbuf-animation.obj' was created with an older compiler than other objects; rebuild old objects and libraries If I disable Link Time Code Generation I see this error instead:-
fatal error C1900: Il mismatch between 'P1' version '20060201' and 'P2' version '20050411'
It only seems to affect this one project (and even then, only the Release build). I've even restored a backed-up version of the vcproj file but it's no different.
I am facing a problem in C++,I want to execute a command in Command prompt from a specific path.I am able o select a path and execute cmd.exe using the function ShellExecute but the problem is after selecting the path I am not able to execute the command, the command is appearing on another command prompt.
View 4 Replies View RelatedI wrote a program to run long simulations, in one cpu core computation. During the run, I checked the cpu occupation was always around 85%.
Since my simulation took time to run. How can I boost it up to make my cpu run at 100%? Is that because my RAM is not fast enough?
info about my laptop: cpu frequency: up to 3.2 GHz. RAM frequency: 1333 MHz.
I want to write a function and be able to call it during execution (say during a while(1) loop). Is this possible without having to parse an input string to extract the function and parameters I need or is that the only way?

I would like to know how to prevent the program print out "Business", I'd like it to call the base class's static function. I have tried to changed MyClass* into void* but it still prints Business :grumpy:.
My challenge is to output "BusinessInterop" without any changes made to the polymorphic structure as designed.
how the output for the program below comes to 45 and 46 respectively.

We create an unnamed array "on the fly" that it means array has no permanent storage during the program execution?
This question is currently only for windows; but I would like to know about a cross-platform way to perform what I want to do (explained below) -
I have created a little program:
#include <iostream>
int main(int argc, char *argv[]) {
for (int i = 0; i < argc; ++i) {
std::cout << argv[i] << '
';
} }
I have added this program to the windows PATH. I put this program in C:Program FilesProgram
I now navigate to C:DataVariousTexts using CMD.
Then I type in: "program x"
The program will print out "program x" as by default. What I would like to get hold of is the folder in which the program is actually being called. ( I want to somehow get "C:DataVariousTexts" to be read into my program ).
How do I perform such an operation?
I have a method that changes a canvas color after set intervals, e.g. start timer, 5 seconds green, 3 seconds red, then stop. This functionality is provided in the interval method. The problem I'm trying to achieve is getting this sequence to repeat for a set number of iterations.
I tried to solve this by setting up a counter after the timer is stopped but the code keeps repeating indefinitely by starting and stopping over and over instead of the max of 6 iterations I had set. In debugging the problem, I watched the value of 'i' and when the 'if' statement is set to false. The 'if' statement gets set to false after 7 iteration as expected but the start(); keeps getting called.
void myTimer_Tick(object sender, EventArgs e) {
//Assign text box string value to a time span variable.
TimeSpan workTm = TimeSpan.ParseExact(wrkString, @"hh : mm : ss : fff", CultureInfo.InvariantCulture);
TimeSpan restTm = TimeSpan.ParseExact(rstString, @"hh : mm : ss : fff", CultureInfo.InvariantCulture);
// update the textblock on the display
// with hh, mm, ss, ms
ms = myStopwatch.ElapsedMilliseconds;

This is the problem:
1+2+3+...+n=(n(n+1))/2
Write a C++ program that compares the execution time of the above summation using two different solutions: one that uses loops, and another that uses the closed form approach. Use large values of n for the comparisons, such as, 10^7, 10^8, 10^9, 10^10, 10^11,10^12, 10^13, and 10^14. Provide a comparison table for the execution time in both solutions.Do not worry about the value of the actual sum. Overflow will occur in the sum value rendering it invalid; however, this is not the primary concern of the program. Execution time is the primary concern.
I have a for loop, and after this loop, I am calling another function that wakes a thread S, and then thread S carries on its execution.
Code:
for (k = 0; k < num_msg; k++) {
if( (c % Messages[k][2] ) == 0 ) {
printf("
%d, act, %d
[Code]....
I am getting an anomalous output. Before all the iterations of for loop could finish, the program enters into the invoke_thread_S() and I can see the remaining iterations of for loop happening after thread S is finished.
What could be the problem here. Can I put a 'sleep' before I enter into invoke_thread_S() function, I tried it with a very small amount (in nano seconds), but that did not solve the problem.

I have a program including several code blocks in the following simplified structure:
int main() {
// block A
if(a > 0) {
}
// block B
if(a > 1) {
} }
Block A and B should be executed separately, according to entry from keyboard. For example, if entry "1", block A will be executed and block B will be ignored; if entry "2" the inverse will happen.
I can control the execution of these two blocks through macro but the code will be separated during compilation. But is there a way to control them without using macro?
I got a assignment in which i have to write codes for execution of certain commands.
One of the command is set_time. if user enters set_time 12:12:12
The time should get reset to 12:12:12 no matter what it is now.
how we will increase the size of an arry during program execution. eg if the size of an array is 40 and during prog exexution we want to increase the size of an arry ,what is the procedure.
View 1 Replies View RelatedI 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 ?
I know there has to be a system call to pause (not system("pause") execution of a program for a few seconds. I would like to give the illusion that my program is 'thinking' rather than just spit out the result as soon as the user has hit the enter key.
