Answer 1

Uses crt;
var i,s:integer;
a:array[1..5] of integer;
begin
randomize;
s:=0;
for i:=1 to 5 do
begin
a[i]:=random(15)-5;
if a[i]>0 then s:=s+a[i];
end;
writeln(s);
readln;
end.

uses crt;
var i,s:integer;
a:array[1..7] of integer;
begin
s:=0;
randomize;
for i:=1 to 7 do
begin
a[i]:=random(15)-5;
if ((a[i]>0) and (a[i] mod 2 = 0)) then inc(s);
end;
writeln(s);
readln;
end.

uses crt;
var i,s:integer;
a:array[1..6] of integer;
begin
s:=1;
randomize;
for i:=1 to 6 do
begin
a[i]:=random(15)-5;
if (a[i]>0) then s:=s*a[i];
end;
writeln(s);
readln;
end.
