for (int z = 0; z < 5; z++) { if (( y-- > 7 ) || (++x > 2)) { y--; } }

z=0: (y-- > 7) is true and do y--; //x =0 y =8 z=1: (y-- > 7) is true and do y--; //x =0 y =6 z=2: (y-- > 7) is false and continue to evalute (++x > 2) which is false //x=1 y=5 z=3: (y-- > 7) is false and continue to evalute (++x > 2) which is false //x=2 y=4 z=4: (y-- > 7) is false and (++x > 2) is true then doing y--; //x=3 y=2
