Cái này mình viết chương trình chính thôi, bạn tự viết ctc nhé
Câu 1:
uses crt;
var n,i,s:longint;
begin
clrscr;
write('Nhap n='); readln(n);
s:=1;
for i:=1 to n do
s:=s*i;
writeln(s);
readln;
end.
Câu 2:
uses crt;
var st:string;
i,d:integer;
begin
clrscr;
write('Nhap xau:'); readln(st);
d:=length(st);
for i:=d downto 1 do
write(st[i]);
readln;
end.
