Thread: Help with an error with Sleep()

I have used Sleep() before in another program and never had any problems, but this time when I compile it is telling me that Sleep is an undeclared identifier. I #included <ctime> like I did the last time I used it, but it doesn't want to work this time. Hopefully someone can find what I did wrong and let me know.
Thanks

Code:

#include "Date.h"
#include "Classroom.h"
#include <iostream>
#include <ctime>
#include <fstream>
#include <string>


using namespace std;

template <typename T>
void sortArray(T array[], int size);
void printArray(Classroom array[], int size);
void openFile(ifstream& fin);
int fillArray(ifstream& fin, Classroom array[]);


int main()
{
	Classroom c_array[20];
	ifstream in;
	int rooms;

	
	openFile(in);
	
	rooms = fillArray(in, c_array);
	
	printArray(c_array, rooms);
	system("pause");
	system("cls");
	
	sortArray(c_array, rooms);

	printArray(c_array, rooms);
	
	system("pause");
        
               return 0;

}

int fillArray(ifstream& fin, Classroom array[])
{

	Classroom temp;
	int i=0;
	int no_rooms;
	
	fin >> no_rooms;
	fin.ignore(200, '\n');
	
	temp.ReadClassroom(fin);
	while(!fin.eof() && i <= no_rooms)
		{
		array[i] = temp;
		temp.ReadClassroom(fin);
		i++;
		}
	return no_rooms;
}


void openFile(ifstream& fin)
{
	fin.open("a:studentData.txt");
	if(fin.fail())
	{
		cout << "Error opening file";
		system("pause");
		exit(1);
	}
}

void printArray(Classroom array[], int size)
{
	cout.setf(ios::fixed);
	cout.precision(0);

	for(int x=0; x<size; x++)
	{
		array[x].PrintStats(cout);
		Sleep(1000);//<<<<<<<<<<<<<<	
                }
}


template <typename T>
void sortArray(T array[], int size)
{
	int pass, j;
	T temp;
	int smallIndex;

	for(pass = 0; pass < size-1; pass++)
	{

		smallIndex = pass;

		for(j= pass+1; j < size; j++)
		{
			if(array[j] < array[smallIndex])
				smallIndex = j;
		}

			if(smallIndex != pass)
			{
				temp = array[pass];
				array[pass] = array[smallIndex];
				array[smallIndex] = temp;
			}
		
	}
	

}

Sleep() is in windows.h i think.

Thanks Hybrid, that worked But it still remains a mystery why my last program was bale to use Sleep() without includeing windows.h? I hate things I can't figure out. Well as long as it works now.

I bet that's what it was. I have a header written by someone that allows me to use colors and that may be it. Thanks for the info

I'm not sure what compiler/IDE you're using, but with MSVC++, (and I assume with other compilers) you can always go to the compiler's help index and type-in the function name. It'll tell you which header file it's in.

Noobie,

Sleep() pauses execution while allowing other programs (in other windows, etc.) to run.

This is NOT standard ANSI C++ !!! (So your compiler might not have it.)

I am running .Net and I know it has it. It must have been another header I was including that was already using it's header.

im pretty sure that you need to include <window.h>.
I used to have the same problem with using Sleep() until i found out about this header file
