C++ Pause

[nothvice]

Hello.

I am trying to understand a C++ snake program I encounted on the net and can't seem to understand the following line:
for (int i=0;i<(speed*pause_length);i++) int j=1+i

I understand what the loop is doing, but I don't understand how it controls the speed of the game. pause_length is a const variable set to 500000 and speed is set at 80. How does this control the speed of the game?

Thanks

It is an old technique to delay by simply doing a loop for a while. This worked on older computers (like the 8086) where it was slow enough for such things to make sense. These days, it does not.

Instead, use an OS-specific delay function, such as the following

For that you only really need one variable -- the number of milliseconds to delay (the "speed").

Hope this helps.

What header file should I include? I am using Dev C++?

Simply copy and paste the code I gave you.
