Is it too much to ask a computer to do do 2 billion iterations of a single assignment?
I mean with a 2 GHz clock, the CPU can do 2 billion instructions per second, so theoretically a single for loop with a single assignment will have: 1 comparison, 2 assignments and 1 branch per iteration. That shouldn't be too much to ask from a computer right? Then why has the computer been executing this loop for over 10 minutes?
PS: the language is tcl.
There is no way to make a mistake in a single line loop like this:
for {set i 0} {$i < 2147483648} {incr i} {
set arr($i) $i
}

You made a mistake in the loop, and that why it is taking so long.
