About LinkBacksOK I feel really stupid for this, but I can't get it to work. I thought you just needed #include<time.h> at the top to use it, but obviously not, so can anyone tell me what it should be instead of time.h please?
This is a discussion on 'wait' undeclared? within the C++ Programming forums, part of the General Programming Boards category; OK I feel really stupid for this, but I can't get it to work. I thought you just needed #include<time.h> ...
'wait' undeclared? OK I feel really stupid for this, but I can't get it to work. I thought you just needed #include<time.h> at the top to use it, but obviously not, so can anyone tell me what it should be instead of time.h please?
perhaps this?
Code:#include <ctime>

Code:void wait ( int seconds ) { clock_t endwait; endwait = clock () + seconds * CLK_TCK ; while (clock() < endwait) {} }
That is a very bad wait function consider what it is doing... you are putting it into an loop where it will be sucking up the processor hardcore. A better solution is Sleep/sleep, search it on the board to find a nice function that is crossplatform
You're right, Sleep(); is better. That's in milliseconds, right? So, Sleep(1000);
Yes, it's in milliseconds. Sleep(1000); is about 1 second. Make sure to:However, it's platform dependent!Code:#include <windows.h>

Oh and remember the uppercase issue with sleep().
In C it is:
sleep(1000);
In C++ it is:
Sleep(1000);
Very easy mistake to make

You're kidding, right?
C and C++ don't have sleep() as part of the standard.
I believe its Sleep() - the WinAPI, and sleep() - the windows.h function.

Sleep() - win32
sleep() - *nix
Or did our friend want this wait()...Code:void wait(size_t ms) { #ifdef WIN32 #include <windows.h> Sleep(ms); #else #include <unistd.h> usleep(ms); #endif }

Code:#include <stdio.h> void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){ puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9 /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i] ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][ t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}
I ... don't think it's a very good idea to include headers within functions.
Oh no, I really don't.
What happened to the xp_sleep functions I posted a few weeks back? The board can't find them, and neither can the other board at which I post regularly.
