Hi,

I have a constant stream of data coming into my c++ console application and i want to display this data on the console.

the problem is that since the amount of data received is huge I end up slowing the whole PC is there a way i can solve this problem (double buffering ??) if so can you point me to an article of example of how this is conducted

(i am currently using a simple cout with output the data)

Bad idea, period!
If there is that much data that it is slowing down the whole PC, how do you expect the user to read it?
You need to look at either summarizing the data, or presenting it in a fixed page size.

At the moment, you are just adding more and more data to the output, causing more and more lines of text to be scrolled, which is why it slows down.

so there is now way to do this?
honestly idk if the user doesn't get time to read the text.. as long as the pc doesn't slow down (note if i minimize the console cmd the pc doesn't slow down)

Try to look at it through the eyes of the user:

What does he want to see?
What does he need to see?

Maybe all that's relevant is some kid of status, and it might be sufficient to update it once or twice a second.

If the user really needs to be able to see the actual data, then convert it to something that's both compact and visually meaningful, such as a single dot in a function graph. You could make a display similar to the systems performance meter, using double-buffering to redraw the graph a couple of times per second.
