Bài 1:
Program hotrotinhoc_hoc24;
var i,n: integer;
begin
write('Nhap n='); readln(n);
i:=0;
while i<10 do
begin
i:=i+1;
writeln(n,'*',i,'=',n*i);
end;
readln
end.
Bài 2:
Program hotrotinhoc_hoc24;
var i,n,d,d1: integer;
begin
write('Nhap n='); readln(n);
i:=0;
while i<n do
begin
i:=i+1;

Cách 1 dùng lệnh for do:
Uses crt;
var i,n,k: integer;
begin clrcsr;
readln(n);
for i:=1 to n do begin
if(i mod 2=0) and (i>=10) then k:=k*i;
end;
writeln(k);
readln;
end.
Cách 2 dùng lệnh while do
Uses crt;
var m,n,o: integer;
begin clrcsr;
readln(n);
o:=1;
m:=1;
while (m<n) do begin
m:=m+1;
if(m mod 2=0) and (m>=10) then o:=o*m;
end;
writeln(o);
readln;
end.
uses crt;
var i,n:integer;
begin
write('nhap n=');readln(n);
writeln('bang nhan',n);
for i:=1 to 10 do writeln(n,' x ',i:2,' = ',n*i:3);
readln
end.
var n, sum : integer;
begin
write('Nhap n: ');
readln(n);
sum := 0;
while n > 0 do
begin
sum := sum + n;
n := n - 1;
end;
writeln('Tong la: ', sum);
end.
program Le_Nho_Hon_Hoac_Bang_n;
uses crt;
var
n, i: integer;
begin

while n <= 0 do
begin
writeln('So ban nhap khong hop le. Xin vui long nhap lai: ');
readln(n);
end;
clrscr;
writeln('Cac so le nho hon hoac bang ', n, ' la:');
i := 1;
while i <= n do
begin
if i mod 2 <> 0 then
writeln(i);
i := i + 1;
end;
readln;
end.
