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. написал на pascalabc.net заранее .

Answer 1

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.

Answer 2

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;
