Is there any overhead to declaring a variable within a loop? (C++)
...pe. So no stack pointer adjustment happens inside the loop, just assigning 4 to var. Therefore these two snippets have the same overhead.

What are bitwise operators?
... For example, reading an integer from four bytes:
int val = (A << 24) | (B << 16) | (C << 8) | D;
Assuming that A is the most-significant byte and D the least. It would end up as:
A = 01000000
B = 00000101
C = 00101011
D = 11100011
val = 01000000 00000101 00101011 11100011
