1) Variabilele x,y si z sunt de tip intreg si memoreaza valori distincte.Indicati o secventa de instructiuni in urma executarii careia se realizeaza interschimbarea valorilor variabilelor x si y. a) x=y; y=z; z=x; b) z=y; y=x ;x=z c) z=x ;z=y ; x=y; 2) Indicati valoarea expresiei C/C++ alaturate: 21/2*2-5 a) 0 b) 15 c) 0.25 3) Variabilele x si y sunt de tip intreg.Indicati o pereche de valori pentru expresia urmatoare:(x%100==y%100)&&(x>99)||(y>99) a) x=1100 si y=10 b) x=30 si y=30 c) x=1003 si y=3 4) Indicati o expresie C/C++ care are valoarea 1 daca si numai daca numerele naturale memorate in variabilele intregi x si y sunt pare consecutive. a) x-y==2 b) ( (x-y==2) || (y-x==2)) && (x%2==0) c) (x==2) && (y==4) 5) Variabilele x si y sunt de tip intreg,x memorand valoarea 8 iar y valoarea 6.Indicati expresia C/C++ care are valoarea 0. a) 3*x-4==0 b) ! (x/2+2==y) c) x-y+3!=0
