int i = 0, j = 8;

When we use i++ i is incremented, but the old value is used in any enclosing expression
When we use ++i, the new value is used

int a[] = { 3, 2, 1, 0, 4 }, b[5];
for (int i=0; i<5; i++) { if (!(b[i] = a[i])) break; // =, not == cout << b[i] << endl; a 3 2 1 0 4 b 3 2 1 0 ? map marks;
