Imi spune si mie ce am gresit la sursa? Sau...cum puteam sa fiu in timpul de executie?
<Clasa a IX-a>

Cod:

#include<iostream>

using namespace std; // p=numar iarba uscata sub un elicopter q=numar total iarba sub un elicopter :@

ifstream f;

int m,n,k,t[101][101],c[41][41],i,j,h=1,N1=0,N2=0,p=0,sw[101][101],y=0,q=0;

Cea de mai sus este Problema cu Elicopterele ( I ).

Cod:

#include<iostream>
#include<fstream>

using namespace std;

ifstream f;
ofstream g;

int n,p,c[361],cl,rtr,i,j,Euro,oc[361],h=1,sw[361],ultim;
float x,r[361];

void citire()
{
	f >> n >> p;
	for(i=1;i<=n;i++)
		f >> c[i];
}

float inv(int n)
{
	x=1/n;
}

void afisare()
{
	g << Euro << '\n';
	for(h=1;h<=p;h++)
		g << oc[h] << " ";
}
	
int main()
{
	f.open("roata.in");
	g.open("roata.out");
	
	citire();
	
	cl=n;
	
	for(i=1;i<=n;i++)
		rtr+=c[i];
	Euro=rtr;
	
	for(j=1;j<=n;j++)
		sw[j]=0;
	
	while(rtr>0)
	{
		if(cl>=1)
		{
			cl--;
			for(j=1;j<=n;j++)

				{
					sw[j]=1;
					j=n;
				}

				sw[j]=0;

				oc[h]=j;
				h++;
			}
		}

			if(sw[i]==1)
				r[i]+=inv(n);
	}
	
	afisare();
	
	f.close();
	g.close();
	
	return 0;
}

Cea de mai sus este Problema cu Roata ( II ).

Aha...deci...nu este voie sa folosim acel ".txt" la sfarsit. Multumesc.

Am o problema...de fapt nu am...am luat 100 de puncte si o data 0 puncte, iar eu sincer nu inteleg diferenta dintre cele doua solutii.

Acesta este programul corect :

Cod:

#include<fstream>

using namespace std;

int a,b;

ifstream f;
ofstream g;

int main()
{

f.open("adunare.in");
f >> a >> b;
g.open("adunare.out");
g << a+b << endl;

f.close();
g.close();

return 0;
}

Iar, acesta este cel gresit :

Cod:

#include<iostream>
#include<fstream>

using namespace std;

int a,b,S;

ifstream in;
ofstream out;

int main()
{
in.open("adunare.in.txt");

in >> a;
in >> b;

S=a+b;

out.open("adunare.out.txt");
out << S;

return 0;
}

Singura diferenta este cea ca in cel gresit am adaugat fisierul iostream.h. Nimic altceva? De ce reprezinta o problema?
