First we need to know if the app have load time at all. Else we would have to fake the load bar

[maculhet]

there is none it's just an effect for my project...thnx

[MrHutch]

Why on Earth would you want a fake loading screen!?

[maculhet]

like i said its just an effect...to make my project more creative...

[MrHutch]

Fair enough, though I'd hope a program would open up fast as possible.

I can't remember if C++ has a sleep function or not. I'll write one for you. Let's call it Wait(). You'll need to include the ctime header.

#include <iostream>
#include <ctime>

using namespace std;

void Wait(int seconds)
{
    bool waiting = true;
    int fc, cc; // First click, current click

    fc = clock();

    while(waiting)
    {
        cc = clock();
        if( ((cc - fc) / CLOCKS_PER_SEC) > seconds )
            break;
    }
}

int main(int argc, char *argv[])
{
    cout << "Hello ";
    Wait(2);
    cout << " world!";
}

Obviously the bit you'd need is the Wait function. I just included the main to show it working.

If you want it in a loading bar, just put it in a loop or something, printing out an asterisk at each iteration.

Note: It's a quick and dirty function, I'm afraid. Just don't do anything silly like pass -1 into it. ;-)

thank you so much this will help so much...very much appreciated...

If youre on windows i would recomend using Sleep(). It's very simple, but your program will be platform dependent

[samrux]

Ok, so the most simple way of doing this is...

#include <iostream>
#include <windows.h>
using namespace std;

int main(){
    cout << "\n\n *\n *";
    Sleep(500);
    system("cls");
    cout << "\n\n **\n **";
    Sleep(500);
    system("cls");
    cout << "\n\n ***\n ***";
    Sleep(500);
    system("cls");
    cout << "\n\n ****\n ****";
    //Etc, your code
    cin.sync(); cin.ignore();
}

@maculhet

Actually, an even simpler way is..

#include <iostream>

using namespace std;

int main()
{

    cout << "\n\n *";
    for(int a=1;a<8;a++) // Change 'a<?' to how many * you want
	{
		Sleep(500);
		cout << "*";
	}
    //Etc, your code
    cin.sync(); cin.ignore();

No need to clear screen, or even to #include windows.h, unless you need it for other parts of your program.

^You need windows.h for Sleep().

^Whoops, you're right. ( *** BRAIN FART *** ) !!
