how to delay in C++???

[Mukul Kumar]

i am not able to use sleep function in C++ by windows.h
so i need a substitute function which takes milliseconds as arguments!!!

Why not?

It takes milliseconds as a parameter
Sleep function (Windows)

[Mukul Kumar]

only one error and these warnings!!!
the tournament.o:the tournament.cpp.text+0x5b): undefined reference to `sleep(int)'
the tournament.o:the tournament.cpp.text+0xfd): undefined reference to `sleep(int)'
the tournament.o:the tournament.cpp.text+0x17f): undefined reference to `sleep(int)'

You may want to study the link Salem provided, and notice the difference in spelling and remember C/C++ is case sensitive.

For that matter, how are you able to call sleep(...) in the first place? It doesn't exist, so it should generate a compile error. You didn't add some prototype manually, did you?

[Mukul Kumar]

ummm..... no nothing is working i included the windows.h file + looked for all spell mistake and after that still this function is undefined!!!(some of you might think that i am just lying but i am serious)

[jimblumberg]

Then post your code that exhibits the problem so maybe we can see what you're doing wrong.

How did you spell the function sleep() or Sleep()?

And how did you spell windows.h?

there are 12 files including a header file but i'll show the one with int main()

Look closely at the following snippet:

void noem()
{
    system("cls");
    cout<<"you have not enough money to buy this item...\n";
    sleep(2000);

Is that how Sleep() is spelled in the Microsoft documentation you have been provided. C/C++ is case sensitive.

oh kayy then tell me is it small 's' or capital one???

[Elysia]

It is not and has never been "sleep". It always has and always will be "Sleep".
And fix those global variables.

[Mukul Kumar]

oh kayyyy got it its capital one i'll take care now actually i thought that its rare that we declare a function with capital letters!!! thanks
jim

[Elysia]

It's not rare. It's a matter of style.
Windows API functions are typically written LikeThis.
The C++ standard library is typically written like_this.
I tend to use a mix of both. It's a matter of style, and neither style is that rare.

[Mukul Kumar]

thanks Elysia i'll take care for that too!!
