New Answerfrom left to rigt, at each addition step of expression; x = i++; // <=> x += 1 (x == 1) // x += (i == 1); (i += 1) == 2; x += i++; // <=> x += 2 (x == 3) // x += (i == 2); (i += 1) == 3 x += ++i; // <=> x += 4 (x == 7) // (i += 1) == 4; x += (i == 4) x += i++; // <=> x += 4 (x == 11) // x += (i == 4); (i += 1) == 5 x += --i; // <=> x += 4 (x = 15) // (i -= 1) == 4; x += (i == 4) x += ++i; // <=> x += 5 (x = 20) // (i += 1) == 5; x += (i == 5) x == 1+2+4+4+4+5 == 20

Yep, that's all about abusing increments , but helps at undestanding how it works soooooo much :) Good Job :) It broke my brain once again even if I solved it like mounth ago , so I posted it for others :D Visps's answer had most info , so his answer will be best I guess , he deserves it :)
