A question about integers

Will

Code:

---

int i = 10000000;
i++;

---

take more time to process than

Code:

---

int i = 0;
i++;

---

?

No.

They will both compile down to

Code:

---

push 1000000
inc [%%sp]

---

and

Code:

---

push 0
inc [%%sp]

---

IMO both your assembly variants are unlikely. The OP's code shows no reason to push the int at all because it's not going to be passed as a function parameter.

I'd say discussing assembly details here is moot anyway and not really helpful to the OP... ;)

EDIT: Ok, I need to take back my statement about no need to push the int as the variable is just being constructed. :o Looks like I wrote the post too quickly. But the second paragraph still holds true IMO...
