i, count: integer;
begin
writeln('Vvedite stroky: ');
readln(s);
for i := 1 to length(s) - 2 do
if copy(s, i, 3) = 'abc' then
count := count + 1;
writeln('Kol-vo: ', count);
end.

var
s1, s2: string;
i, len1, len2: integer;
begin
writeln('Vvedite stroky 1: ');
readln(s1);
writeln('Vvedite stroky 2: ');
readln(s2);
len1 := length(s1);
len2 := length(s2);
if len1 > len2 then writeln('1 stroka dlinnee')
else if len1 < len2 then writeln('2 stroka dlinnee')
else writeln('dlini strok ravnie')
end.
