Blink a random number on the screen? Do you want to show this number in the console, just printed with cout?

@boxfish
yaa blink the number on console

[boxfish]

Pseudocode goes something like

while (true) {
    wait for 10 ms
    generate random number
    display number
    wait for 10 ms
    backspace number
}

Which of these things are you having trouble with?

How to wait for 10ms exactly?

[boxfish]

the clock() function from the <ctime> include file tells you how many clock ticks have passed since your program was launched. You can divide it by CLOCKS_PER_SEC to get this length in seconds. I would define a constant
CLOCKS_PER_10MS = CLOCKS_PER_SEC / 100;
So to wait for 10MS, Take the current clock value, add CLOCKS_PER_10MS to it, and use a while loop to wait for clock to be greater than that value. It should actually be very similar to the wait() function in the example on the page I linked to.
I hope this is helpful.
