c++ programming part four

459. Statement:
460. x = ++ i;
461. represents the abbreviated writing of the statement sequence:
462. i = i + 1;
463. x = i;
464. After executing the statement x = ++ and the variables have values i = 2 and x =
2.
465. Example. Either the variable:
466. int j = 3, k;
467. Statement:
468. k = --j;
469. represents the abbreviated writing of the statement sequence:
470. j = 1;
471. k = j;
472. After executing the statement, the variables have the values ??j = 2 and k = 2.

473. The postfix operators, x ++, x--.

474. The value of the expression is even the value of the variable (unincremented or
475. count down). It increments / decrements then variable.
476. Example.
477. Either the two statements:
478. int a, b;
479. b = 3;
480. a = b ++;
481. expression:
482. a = b ++;
483. corresponds to the sequence of statements:
484. a = b;
485. b = b + 1;
486. Consequently, the expression b ++ has the value 3 (value
unincremented variable) and then increment b.
487. We have the result:
488. a = 3
489. b = 4
