c++ - Bitshifting on little-endian and big-endian -


this question has answer here:

will this:

((0x10203040 >> 24) & 0xff) == 0x10

always true on both little-endian , big-endian machines?

yes. endianness affects how bytes stored in memory. value of 0x10203040 270544960 regardless of whether it's first or last byte in memory 0x10.

to gratuitously borrow images wikipedia article on endianness, regardless of of these layouts our system uses:

the value of 0x0a0b0c0d still same.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
