Tortoise/Hare clock question

This is a problem from Deitel & Deitel's C++ How to Program(pg. 386,prblm. 5.17). It is a tortoise/Hare race simulation. In the beginning of the program description it states, "There is a clock that ticks once per second. With each tick of the clock, your program should adjust the position of the animals according....".

My question is how do you set up a loop that executes once per second?

This hasn't been taught in the book and any examples haven't been given so I'm stuck at the beginning.

Code:

---

#include <windows.h>

for (...)
{
    Sleep(100); // 100 miliseconds
    ...
}

---

Sounds good and possibly the only and or best solution, but if you sleep for one second each time you do not take into account for the time of execution of the process between the loop. This will make each cycle through the loop slightly more than one second.

True, but I´m pretty sure that you will not notice that (cycle)delay.

Can you help me debug this code now that it is almost complete?

Code:

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <windows.h>

using namespace std;

int main(int argc, char *argv[])
{
   
  srand(time(0));
 
  int position_tortoise, position_hare=1;
 
 
  while (position_tortoise && position_hare <70){
    Sleep(100);
   
    int tortoise_decision, hare_decision=0;
   
    tortoise_decision=rand()%10+1;
    hare_decision=rand()%10+1;
   
    if (tortoise_decision<=5)
        position_tortoise=position_tortoise+3;
    if (hare_decision<=2)
        position_hare=position_hare;
    if ((tortoise_decision>5)&&(tortoise_decision<=7)){
        position_tortoise=position_tortoise-6;
        if (position_tortoise<1)
                position_tortoise=1;
    }
    if ((hare_decision>2)&&(hare_decision<=4))
        position_hare=position_hare+9;
    if (tortoise_decision>7)
        position_tortoise=position_tortoise+1;
    if ((hare_decision>4)&&(hare_decision<=5)){
        position_hare=position_hare-12;
        if (position_hare<1)
          position_hare=1;
    }
    if ((hare_decision>5)&&(hare_decision<=8))
        position_hare=position_hare+1;
    if ((hare_decision>8)){
        position_hare=position_hare-1;
       
    for (int print_position=1;print_position<=70;print_position++){
        if ((position_tortoise==position_hare)&&(position_hare==print_position))
            cout << "OUCH";
        if (position_tortoise==print_position)
            cout << "T";
        if (position_hare==print_position)
            cout << "H";
        if (!((position_tortoise==position_hare)&&(position_tortoise==print_position)&&(position_hare==print_position)))
            cout << " ";
    }
  cout << endl;
   
 
   
     
 
  }
  if ((position_tortoise==position_hare))
    cout << "It's a tie!"<<endl;
  if ((position_tortoise>position_hare))
    cout << "Tortoise wins!"<<endl;
  if ((position_hare>position_tortoise))
    cout << "Hare wins!"<<endl; 
 
  system("PAUSE");       
  return 0;
}

You have a } missing from somewhere in there.

Actualy its and extra } i belive
i see 4 { and } 5

On a sidenote, Sleep(100) sleeps for 100ms which is 1/10 of a second, not one second.

Err no, I count 6 open and 5 close, or at least the find feature of my editor does. ;)
