9.35. n (n=7) o'lchovli chiziqli fazoda n ta vektorning koordinatalari berilgan. Bu vektorlar chiziqli erkli bo'ladimi?

9.36. n (n=6) tartibli kvadrat matritsa berilgan. Ushbu matritsaga teskari matritsa topilsin yoki bunday matritsa mavjud emasligi aniqlansin. (Izoh: agar berilgan matritsani satrlarini chiziqli almashtirish yordamida birlik matritsaga keltirilsa, xuddi shunday almashtirishlar yordamida birlik matritsa izlanayotgan teskari matritsaga keltiriladi).

10. Satrlar

10.1. Quyida berilgan turlarning qaysi birlari satrli tur hisoblanadi yoki yo'q va nima uchun?

const n=20;

type a = array[1..30] of char;

b = array[1..n] of char;

c = array[0..n] of char;

d = array['1'..'9'] of char;

e = array[1..n,1..n] of char;

f = array[1..10] of char;

g = array[1..1] of char;

10.2. const n=5;

var a1, a2: array[1..n] of char;

b1, b2: array[1..n] of char;

c: array[1..5] of char;

Quyida keltirilgan amallarning qaysi birlari Paskalda o'rinli:

a) a1:=a2; b) b2:=b1; v) a1:=b1;

g) s:=a2; d) a2:='b1+b2'; e) b1:='12345';

j) s:='abc'; z) a1

k) a2>s; l) s>='12345'; m) a1<>'**';

n) read(c); o) write(a1,'=',a2); p) writeln(b1);
