Question : How do I send a message from server to clear client screen?

I am writing a small memory game that runs on a network. The server generates 10 random numbers, sends them to the client, and the player then types in the 10 numbers from memory. I need to display the ten numbers, wait 10-15 seconds, then clear the screen. I was using the sleep() function to do this, but sleep is executing before the generate_game function, meaning the client sees a blank screen for 10 seconds, then the game flashes for a millisecond and the screen is blank again.

I've also tried putting the sleep at the end of generate_game, and at the beginning of clear_screen. Always the same result.

Why is it doing this and how can I fix it? (It's in C++.)

Thanks!

Code Snippet:

1: 2: 3:

generate_game(); //generates a string of 10 random ints and sends to client sleep(10); clear_screen(); //sends a string of newlines to client

>> but sleep is executing before the generate_game function

The problem is likely that you are using a buffered output, and that the output buffer hasn't been flushed to the screen yet. Can you show the code for generate_game() ? Specifically the part that shows the values to the user ?
