infinite loop?multiples of 2/
Is this code logically corrrect.In order to make it infinite what condition/s should be used.Code:/* #include<iostream> #include<conio.h> using std::cout; using std::cin; using std::endl; int main() { // declare variables int x,counter; cout<<"\n\n\t\t"<<2; // print squares for(x=2;x<=counter;x*=2) { cout<<"\n\n\t\t"<<x*2; } getch(); }
Is the code correct. Doubt it. Especially as counter is unitialised to anything at first use.
Infinite loop.... easy....
Code:while ( true ) { // blah blah if ( some condition ) break; }
Free the weed!! Class B to class C is not good enough!!
And the FAQ is here :- http://faq.cprogramming.com/cgi-bin/smartfaq.cgi
Alternatively:
Code:for( ; ; ) { // ... etc ... }
The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.
Infinite loop the functional way:
Not very good in C++, though. In fact, don't use it.Code:template<typename F> void infinite( const F& f ) { f(); infinite(f); }

Okay, let's do it the easy way:
-SirCrono6Code:#include <iostream> using std :: cin; using std :: cout; int main(int argc, char *argv[]) { int X = 1; while(X = 1) { cout << "Infinite loop printing this... "; } cin.get(); return 0; }
From C to shining C++!
Great graphics, sounds, algorithms, AI, pathfinding, visual effects, cutscenes, etc., etc. do NOT make a good game.

Well, while 'X = 1' will always be true. Did you mean 'X == 1', though? At any rate, I fail to see how that is easier or more elegant than 'while(true)' or 'while(1)'.

or you could use a forever for loop.....
Code:for (;;) //forever loop.... { do something if ( something ) { break; } }

Everyone's right but they didn't point out that you have to have an exit condition to exit these types of loops save stoned coder and littleweseth and you'd have to do something to modfy the value of "X" n SirCronos' code. (Sang-drax's may eventually drain your system resources; infinite recursion as opposed loops run you out of memory).

Well just going by what was given, the only thing the original poster requested was a change to make the loop infinite. They never said anything about breaking out of it.Originally posted by WDT

Quzah.
Hope is the first step on the road to disappointment.
Show them how to jump off the edge of the cliff because they asked; but not how to fly eh quzah??
It's their decision to jump and their fault if they break their neck
All the buzzt!
