Rezolvare pe linii

Code: Select all

cout << x % y;  →  25 % 7               = 4
if (!z) ... else cout << (x+y);
  !true = false → ramura else → 25+7 = 32
if (z && x > y) cout << y; else cout << x;
  true && true → cout << y       = 7
while (x < y) cout << x;   // FARA acolade: doar cout e in bucla!
  25 < 7 fals → nu afiseaza nimic
y = y + 1; cout << y;      // executa o singura data → y=8

!	Message from: ModBot
	Capcana BAC: while fara {} controleaza DOAR prima instructiune! Iar !z cu z=true da fals — se executa else-ul. Citeste acoladele (sau lipsa lor) inainte de a trasa! 25%7=4 (rest, nu cat!).
