[sohel]

seems to be correct..
.. but watch out for outputs like -0.000.

Thanks I get Ac..

Here is my code.Plz tell me where is the mistakes?
#include<stdio.h>
#include<math.h>

void main()
{
double a,b,c,S,r;
while(1)
{
scanf("%lf %lf %lf",&a,&b,&c);
if(feof(stdin))
break;
S=(a+b+c)/2;
r = sqrt((S-a)*(S-b)*(S-c)/S);
printf("The radius of the round table is: %.3lf",r);
}
}

If any of the sides are zero, the area should be zero.

[J&Jewel]

to....asif
If s=0 then divide error should be occur.....( )/s.
so if s=0 then just print 0.000

I hope u get accepted.

That's The Main Case Of This Problem.
I Think Now You Get AC ASiF.

I dont know, why I am getting so glorious WAs( )in this FALTOO problem.
If you know, why this GLORIOUS thing is happening to me... plz let me know...

[kwedeer]

why I am reciving WA? Any idea, please? All seems to be perfect and task seems to be pretty simple...

Here is my code:

Code: Select all

program Prg10195(input, output);

{$APPTYPE CONSOLE}

uses
  SysUtils;
{simple use of triangle formula???}
var  
  a,b,c,S,res: double;
  resp: string;
begin
    {
  AssignFile(Input, 'in10__.txt');
  Reset(Input);
  AssignFile(Output, 'out10__.txt');
  Rewrite(Output);}
  while (not Eof) do begin
    read(a);
    read(b);
    read(c);
    if ((a=0.0) or
        (b=0.0) or
        (c=0.0)) then begin
      res:=0.0;
    end else begin
      S:=((a+b+c)/2.0);
      res:=sqrt(( (S-a)*(S-b)*(S-c) )/S);
    end;
    resp:=Format('The radius of the round table is: %.3f', [res]);
    writeln(resp);
  end;
end.

Thanx for any hint in advance!

Is any established procedure (in the sense of usual quality management practices in software development industry) how to overcome this case - I have code (OK, pretty small - but this is not a issue here) that conforms to all imaginable test cases and it is rejected by judge... OK - usual advice here was - to publish code... I did - but no any feedbacj till now...

I can sey n-time pleaz, pleaz, pleaz - with hope - that it can help...

int main()
{
double a ,b ,c ,r ,s ,s2 ,area;

while (scanf("%lf %lf %lf",&a,&b,&c) != EOF)
{

s = ( a + b + c ) / 2.0;
area = sqrt(s * (s-a) * (s-b) * (s-c));
s2 = a + b + c;
r = 2.0 * area * (1.0 / s2);
printf("The radius of the round table is: %.3lf\n",r);



}

return 0;
}

i wrote this in C!
who can tell me why i got a CE?
thx
