Question

Подскажите, где ошибка:

program mas2;
const
n=5;
type
mas=array[1..n]of real;
var
sr,sum:real;
i:integer;
x:mas;

procedure vvod_rand(var A:mas; n: integer);
var i:integer;
begin
for i:=1 to n do
begin

a[i]:=random(-10,30);
write(a[i],' ');
end;
writeln;
end;

var a:mas;

function sred(var x:mas; s:real):real;
var i:integer;
begin
s:=0;
for i:=1 to n do
s:=x[i]+s;
s:=s/5;
sred:=s
end;

function summa(var x:mas; su:real):real;
var i:integer;
begin
su:=0;
for i:=1 to n do su:=su+x[i];
writeln('sum=',sum);
end;

begin
vvod_rand(a,n);
writeln('sum=',summa(sum,a));
writeln('sred=',sred(a,sr));
end.

Заранее спасибо.

Answer 1

function summa(var x: mas; su: real): real;

var

i: integer;

begin

su := 0;

for i := 1 to n do

su := su + x[i];

summa:=su;

writeln('sum=', su);

end;

Answer 2

Program mas2;
const
  n=5;
type
  mas=array[1..n]of real;
var
  sr,sum:real;
  i:integer;
  x:mas;

procedure vvod_rand(var A:mas; n: integer);
var
  i:integer;
begin
  for i:=1 to n do
  begin
    a[i]:=random(-10,30);
    write(a[i],' ');
  end;
  writeln;
end;

function sred(var x:mas):real;
var
  i:integer;
  s:real;
begin
  s:=0;
  for i:=1 to n do s:=x[i]+s;
  s:=s/5;
  sred:=s
end;

function summa(var x:mas):real;
var
  i:integer;
  su:real;
begin
  su:=0;
  for i:=1 to n do su:=su+x[i];
  summa:=su;
end;

var a:mas;

begin
  vvod_rand(a,n);
  writeln('sum=',summa(a));
  writeln('sred=',sred(a));
end.
