Console Screen update - Iteration Count

[karthigan]

I am writing a simple hardware test program in C that would run from
Windows command line.

Inside one of the loops, I have this code fragment that would display
the Iteration count.

{
....
system("cls");
printf("\nIteration:%d", i);
....
}

Since I have to clear the screen everytime I update the Iteration
count, there is lot of "FLICKERING".

Is there a better way to update the Iteration count without having to
clear the screen?

Regards,
Karthigan.

try something like... should help in reducing the flickering...
{
....
printf("%08d\b\b\b\b\b\b\b\b",i);
fflush(stdout);
.....
}

this subroutine may be useful for you to scratch some ideas.
but if it is far from your problem, just forget it.
void process_bar(void)
{
unsigned int i;
unsigned long j = 0L;

printf("Copying......");
for(i = 1; i < 101; i++)
{
printf("%%%3d", i);
printf("\b\b\b\b");
j = 0L;
while (j < 60000000)
{
j++; /*delay)*/
}
fflush(stdout);
}
printf("\nCompleted!\n");
}
