Andrei Nikolov Compilation Error ??? [9] // Problem 1025. Democracy in Danger 27 Oct 2001 16:27

I recieve Compilation Error when submitting this code: (It
compiles fine on my compiler)?????

#include <iostream.h>

int main() {
int grupi[101] ;
int k, num ;
int sum=0 ;

cin >> k ;
for (int i=0; i<k; i++) {
     cin >> num ;
         if (num==0) grupi[i]=10000 ;
         else grupi[i]=num/2 + 1 ;
     }

for (i=1; i<k; i++)
    for (int j=k-1; j>=i; j--)
      if (grupi[j-1] > grupi[j]) {
        int Temp=grupi[j-1];
        grupi[j-1] = grupi[j] ;
        grupi[j] = Temp ;
        }

for (i=0; i<(k/2+1); i++) sum+=grupi[i] ;
cout << sum ;
return 0 ;
}

У тебя i объявлена внутри цикла, их компилятор это не
понимает. Проси отсылать ответ на E-MAIL, там более
подробная информация.

Ok, which compilator the system uses?

young master Re: Compilation Error ??? [3] // Problem 1025. Democracy in Danger 8 May 2004 12:07

oh shit mine's the same

#include <iostream.h>
#include <stdlib.h>
#define K 101

void main()
{
    int group_num,person_num[K],temp,m,minimal_quantity=0;
    cin>>group_num;
    for(int i=0;i<group_num;i++)
    {
        cin>>person_num[i];
        if(person_num[i]%2==0||person_num<1)
           exit(1);
        if(person_num[i]>10001)
           exit(1);
    }
    for(i=1;i<group_num;i++)
       for(int j=0;j<group_num-i;j++)
          if(person_num[j]>person_num[j+1])
          {
              temp=person_num[j+1];
              person_num[j+1]=person_num[j];
              person_num[j]=temp;
          }
    for(i=0;i<=group_num/2;i++)
    {
        if(person_num[i]==1)
           m=1;
        else
           m=person_num[i]/2+1;
        minimal_quantity+=m;
    }
    cout<<minimal_quantity<<endl;
}

I have the same type of Error. I would post the source but under rules it says not to post source code. It compiles fine on my system and I use gcc that comes with MinGW. The most recent stable version so it should be up to date.

David Payne Re: Compilation Error ??? // Problem 1025. Democracy in Danger 10 May 2004 08:42

Humm, that is very interesting. I got the error because I didn't add a newline character after the last line in my program. And I can't declear and array after the first "executable statement in block". Humm, I think they should update to a C99 standard compiler.

Vladimir Yakovlev (USU) Re: Compilation Error ??? // Problem 1025. Democracy in Danger 10 May 2004 14:53

Maybe instead of

if(person_num[i]%2==0||person_num<1)

you should write

if(person_num[i]%2==0||person_num[i]<1)

nikman Re: Compilation Error ??? [1] // Problem 1025. Democracy in Danger 19 Aug 2004 19:57

for (int j=k-1; j>=i; j--) - error!!!
int j;
for (j=k-1; j>=i; j--) - right!!!

Yosif Yosifov Re: Compilation Error ??? // Problem 1025. Democracy in Danger 20 Aug 2004 05:27

The library u`re using ...

This is how it should be written :

#include <iostream>
using namespace std;

int main() {
int grupi[101] ;
int k, num ;
int sum=0 ;

cin >> k ;
for (int i=0; i<k; i++) {
cin >> num ;
if (num==0) grupi[i]=10000 ;
else grupi[i]=num/2 + 1 ;
}

for (int i=1; i<k; i++) // int i !
for (int j=k-1; j>=i; j--)
if (grupi[j-1] > grupi[j]) {
int Temp=grupi[j-1];
grupi[j-1] = grupi[j] ;
grupi[j] = Temp ;
}

for (int i=0; i<(k/2+1); i++) sum+=grupi[i] ; // int i !
cout << sum ;
return 0 ;
}
