| Yangi mavzu bayoni:
1. Quyidagi ifodalarni o'zlashtirish operatori yordamida yozing.
Javob: y:=(x-21)/(7-exp(63*ln(x)))
b) a=3,6x+sinx; Javob: a:=3.6*x+sin(x)
Javob: z:=sqrt(x-5*y+x*sin(x)/cos(x))
e) Javob: S:=Pi*sqr(r)
f) F=ma Javob: F:=m*a
g) Javob: S:=a*h/2
Chiqarish operatorining natijasi qanday bo'lishini aniqlang.
a) a:=123.45; b) a:=123.45;
write('a=', a:2:l); Javob: a=123.4 write('a=', a:5:l); Javob: 123.4
d) a:= '2011'; e) a:= '2011';
writeln(a:3, ' yil': 3); Javob: 2011 yil writeln(a:4, ' yil': 5). Javob: 2011 yil
3. Dasturdagi o'zgaruvchilarning qiymati turiga mos bo'lishi uchun so'roq belgisi o'rniga zaruriy standart funksiyani yozing va ekranga chiqadigan natijani aniqlang.
a) var a, b, c: integer;
begin a:=25; b:= ?(sqrt(a)); c:= ?(a/b);
writeln(a, ``, b, 'c=`, c);
end.
Javob: b=trunc(sqrt(25))=trunc(5.0)=5; c=trunc(25/5)=trunc(5.0)=5
Ekranda. 25 5c=5
Uyga vazifa: Mavzuni o’rganib kelish.3-(b)mashqni bajarish.
b) var x, y, z: word;
begin
x:=?(?(-7.21)); y:= ?(sqrt(x*x));
z:= ?(x+y-100); write(z-x, y);
end.
Javob: x=trunc(abs(-7.21))=trunc(7.21)=7
y=trunc(sqrt(7*7))=trunc(sqrt(49))=trunc(7.0)=7
z=abs(x+y-100); 7+7-100=14-100=-86 z=abs(-86)=86
z-x=86-7
ekranda: 797
