Question

Cate exercitii vreti va rog mult de tot dau puncte!!!!!

Answer 1

1.
a)
(7-5)%5*10-3 =
= 2%5*10-3 =
= 27

b)
((8+5)-4)*7/8%2 =
=(13-4)*7/8%2 =
= 9*7/8%2=
= 63/8%2=
= 7%2 =
= 1.

c) 11*3/2*2/3*8/4/2=
= 33/2*2/3*8/4/2=
= 16*2/3*8/4/2 =
= 32/3*8/4/2=
= 10*8/4/2 =
= 20/2 =
= 10.

d) (123%10+10*10)-(210/100+15%4) =
= (3 + 100)-(2+3) =
= 103-5 =
= 98

e) 500-(100-30/2/(2+3))=
= 500-(100-30/2/5) =
= 500 - (100-3) =
= 500 - 97 =
= 403

f) 2+3/2+4/2+7 =
= 2+1+2+7=
=12

g) 9*3/6+11*2 =
= 27/6+22 =
= 26

h) 2-3*4/5+(2*3-4) =
= 2-3*4/5+2=
= 2-12/5+2 =
= 2-2+2 =
= 2

i) (16-3*2)%5+11 =
= (16-6)%5+11 =
= 11.


2. max(x%5) = 4

3.
x = 6
y = 3

a)
x-2*y==0
6-2*3==0
6-6==0
TRUE, 1.

b)
x+y>x%y+1
6+3>6%3+1
9>1
TRUE, 1.

c)
x-y<>0
6-3<>0
TRUE, 1.

d)
NOT(x==2*y)
NOT(6==2*3)
NOT(6==6)
0, FALSE

Raspuns : d.


4.
a) FALS
b) FALS
c) ADEVARAT
d) FALS
Raspuns : c.

5. a) Adevarat
b) Adevarat
c) Fals

6. ((a>5) AND (a<20) OR (a<>b)
Echivalenta este expresia “a”

7. (a%10==b%10) && (a>9) || (b>9)
a) a = 1003, b = 3

8.
a) (a>0) && (b>0)
NOT(a<0) && NOT(b<0)

b) (a<0) && (b<0)
NOT(a>0) && NOT(b>0)

Sper ca ti-am fost de ajutor! Succes la scoala!
