Mustaqil bajarish uchun topshiriqlar

1. Arifmetik ifoda qiymatini hisoblang:

1. 
   sin ( sqr ( x ) -1 ) + 2 * abs ( y ) / cos ( 2 + y ) ) bu yerda x = 1, y = -2
   
2. 
   ceil ( 6.9 ) – floor ( 6.2 )
   
3. 
   30 % 6 – 30 % 5 + floor ( 2.7 )
   
4. 
   4 * arctan ( 1 ) – 1 + fabs ( -1 )
   
5. 
   1 + 2.5
   

2. Arifmetik ifoda turini aniqlang:

1. 
   1 + sqrt ( 4 ) + sin ( 0 ) + 0.1
   
2. 
   sqr ( 2.0 ) + sqrt ( 121 ) – ceil ( -11.7 )
   
3. 
   ceil (32.7) + 10 % 3)
   
4. 
   floor ( sin ( 0 ) ) + 1
   

3. Quyidagilardan qaysi biri qiymat berish operatori

а) a := b b) a = c + 1 c) z :- 0 d) y := y f) w := w - 1 е) – y := y f) b := true j) x := 'a' + 1

4. Agar int i, j, k, m; char c, d; i = 1; j = 2; k = -7; m = 0; c = ‘w’; bo’lsa quyidagi ifodalardan qaysi biri to’g’ri yozilgan:

a) d = ’a’+1 < c b) m = - i - 5  j >= k+1 c) i + j++ + k = = -2j

d) m = 3 < j < 5 e) m = 3 = = j < 5 f) m = = c = ’w’

j) m = c != 87 s) m = c = ! 87 l) m = ! c = 87

i) m = !c+87 o) i - k = = ‘0’+9 < 10 p) m ! = c + 87

5. Ifodani C++ tilida yozing:

a) b )

c) d)

e) f)
