Ok that's nice but didn't you forget to say that overall if you just want to increment a variable without caring about post/prefix you should use prefix due to it's lower operation requirement?

Good explanation. Wonder why there's many dislikes.

main()
{
int count, digit=0;
count=1;
while(digit<=9)
{
printf("%d\n", ++count);
++digit;
}
}
Ans is 11
How is it working ?
