Never ending Program

[imgettionowned]

I just started experimenting with loops for c++, so here's a never ending program based upon a for loop.

just compile and run it

Code: Select all

#include <iostream>
int main()
{
	using namespace std;
	cout << "Press Enter When You Want It To Begin: ";
	cin.get();
	int a,b,c;
	b=-1;
	c=100000;
	for (a=0;a = b; a++)
		cout << c++;
	
	cin.get();
	cin.get();
	return 0;
}

It's pretty amazing to watch how fast a pc can actually do math, even though it's as simple as adding one

Edit: I am not sure if it is neverending due to restrictions on how big an integer can get

If you go "unsigned long a, b, c" you can get alot bigger numbers.

Or to create a never-ending loop just test for a condition you know will never return as true. For example:

Code: Select all

int a = 1;
    while (a == 0)
    {
            cout << "Kevin 0nwz j00!!" << endl;
    }

"a" will never evaluate to be equal to zero, therefore it will repeat endlessly.

Actually it will do just the opposite.

Since 'a' will never be evaluated to equal zero, the loop statement will never be executed and the program will end.

What would work for an infinite loop is this conditional

Code: Select all

while (a != 0)

I'm not much of C++ but I think this will work, won't it?

Code: Select all

while(1) 
{
     cout << "[statement] \n";
}

Code: Select all

void main()
{
     yo:
     cout << "Bacon owns joo\n";
     goto yo;
}

Yes that is a common way of processing always true procedures. do() with no while after the ending brace will continue until the condition evaluates false.

Code: Select all

void main()
{
     yo:
     cout << "Bacon owns joo\n";
     goto yo;
}

-- That's nubish >_>

mb:
it also works, and is the easiest way to make a never ending program.
goto mb;

Lol oops. Definately shows how long I've been away from C++. And Goto's are just not cool at all.

Code: Select all

mov	eax, 1		;loop indicator
xor	ebx, ebx 	;resets ebx

loop:
inc	ebx		;ebx+1
cmp	eax, 0		;checks to exit
jne	loop		;otherwise loops

This is just a dummied down version of what you're trying to accomplish in x86 assembly. The only thing wrong with it is there is no way to stop the loop. Stopping the process to quit an application isn't always a good idea ;P

[OwnZ joO]

Not doubting you, but why is it not always good to end a process?

[xbox7887]

Because good applications should be able to quit out themselves...

It's not always good to end a windows process for a large application if it is writing data or nested in a loop modifying the memory. This could just cause a program that saves files to lose or corrupt a file while it's buffering it. Sometimes API functions being interrupted or when a program can't find the proper data in memory at the last address it stored to due to a bug in the software or something else can cause windows to alert you or a memory overflow if a loop persists (pretty rare but it can occur as easily in Internet Explorer with an HTML document).
