#include <iostream>
using namespace std;
int main()
{
int a=0;
for(a; a < 10000000000; a = a + 1 )

}
cout << "value of a: " << a << endl;
return 0;
}
Basic performance program.
If it takes longer than 5 seconds to complete, your machine is under-performing by today standards.

Bet the loop will be optimized away anyway.

not if you disable optimalizations

Shit that fits entirely in the L0 cache is not a good benchmark by any means. It's a nice wake-up call for programmers though, as even such trivial shit can take so much time.

OK

it's been a few minutes and it has not completed

Is this what computer code looks like? I thought it was 0s and 1s?

explain?

that's at the very bottom of the totem pole. programming today uses layers of interpreters, so it has ideally a degree of readability.

This program is too small - it will never invoke reads from RAM. When program becomes too big to fit entirely in the CPU cache(99% of your software) it can become magnitudes slower.

>>58655984
maybe if the variable was declared within the for loop, but since its external, I doubt it would.
