Question

Какое значение получит переменная b после выполнения программы:

program qq;
var a, b: integer;
begin
a := 5;
b := a + 2;
a := (a + 2)*(b - 3);
b := a div 5;
a := a mod b;
a := a + 1;
b := (a + 14) mod 7;
end.
Помогите пж)))

Answer 1

Пройдемся по программе
1. a = 5
2. b = a + 2 = 5 + 2 = 7
3. a = (a + 2) * (b - 3) = (5 + 2) * (7 - 3) = 28
4. b = a div 5 = 28 div 5 = 5
5. a = a mod b = 28 mod 5 = 3
6. a = a + 1 = 3 + 1 = 4
7. b = (a + 14) mod 7 = 4 + 14 mod 7 = 4

Answer 2

a = 5.
b = 5 + 2 = 7.
a = (5 + 2) * (7 - 3) = 7 * 4 = 28.
b = 28 div 5 = 5.
a = 28 mod 5 = 3.
a = 3 + 1 = 4.
b = (4 + 14) mod 7 = 18 mod 7 = 4.
