Mavzuni mustahkamlash:

1.S=0.5+1.5+2.5+…+98.5+99.5 yig`indini hisoblash dasturini tuzing.

Dasturi(While): Dasturi(Repeat):

Var Var

S,k:Real; S,k:Real;

Begin k:=0.5; S:=0; Begin k:=0.5; S:=0;

While k<=99.5 do begin Repeat S:=S+k; k:=k+1;

S:=S+k; k:=k+1; end; Until k>99.5;

Writeln(`S= ` ,S:0:5); Writeln(`S=` ,S:0:5);

End. End.

2. S=1*2+3*4+5*6+…+101*102 yigindini hisoblash dasturini tuzing.

Dastur(While): Dastur(Reperat):

Var S:Longlnt; k:byte; Var S: Longlnt; k:byte;

Begin clrscr; Begin k:=1; S:=0;

k:=1; S:=0;

While k<=101 do begin Repeat S:=S+k*(k+1); k:=k+2;Until k>= 101;

Write(`k=`, k`,S=`,S`,!`); Writeln(`S=`,S);

S:=S+k*(k+1); k:=k+2; end; End.

End.
