C++ :

#include<bits/stdc++.h>
using namespace std;
int a,b;
int main()
{
	printf("17\n26\n35\n44\n53\n62\n71\n80");
	return 0;
}

Pascal :

var
        i,a,b:integer;
begin
        for i:=10 to 99 do
        begin
                a:=i div 10;
                b:=i mod 10;
                if a+b=8 then writeln(i)
        end;
end.
