(9 –sinf ) I bosqich masallar yechimi.
1. Berilgan tomonga ko’ra uchburchak yuzasini hisoblash.

Uses crt; Var a,b,c,S,p:real; begin

Write('a ni kiriting a='); Readln(a);

Write('b ni kiriting b='); Readln(b);

Write('c ni kiriting c='); Readln(c);

p:=(a+b+c)/2; S:=sqrt(p*(p-a)*(p-b)*(p-c));

Writeln('S', S:0:2); Readln; End.
2. Abbos, Abduxalil, Sardor, Toxir so’zlarni ekranda ko’rsatilgan ranglarda 70 marta takrorlab chiqarish.

uses crt; label 1; var x:integer; begin x:=1; 1:x:=x+1; textcolor(x);

write('Abbos'); textcolor(x+0); write('Abduxalil'); textcolor(x+20);

write('Sardor'); textcolor(x+30); write('Toxir'); if x<70 then goto 1;

readln; end.
3. Berilgan ikki sonni bo’lish.

Var a,b:integer; begin read(a); read(b);

writeln(a/b); writeln('Tamom'); end.
4.Berilgan soning tub yoki tub emasligini aniqlaydi.

var

n,i,s:integer;

begin

readln(n);

for i:=2 to n-1 do

if n/i=trunc(n/i) then s:=s+1;

if s=0 then write('tub son') else write('tub son emas');

end.
5. Birdan N gacha 7 ga karrali toq sonlar yig’indisi va ko’paytmasini topish.
Program Akram; Label 1;

var s,i,n,k:integer;

begin

write('n ni kiriting='); readln(n);

s:=0; i:=7; k:=1;

1:s:=i+s; k:=k*i;

i:=i+14;

If i<=n then goto 1;

writeln('Yigindi=',s);

writeln('Kupaytma=',k); readln; end.
