list ... with problems

[cristinelul]

I am a beginner in C++ and needs help ...The program required the user to input integers until input 0; the program must be displayed first- then even numbers and than - odd numbers.Using a list and if the number is even we put it before the first node:prim else ( odd number) we put after the last odd node - ultim. It displays my latest number with all the waters parcurg(prim)

Below is the code:

#include<iostream.h>
#include <stdlib.h>
#include <string.h>
#include <stdio.h>

const unsigned NMAX=100;
struct nod {unsigned nr, urm;};
unsigned liber[NMAX+1], nr_el;
nod lista[NMAX+1];

void init(unsigned &, unsigned &);
int este_plina();
int este_vida(unsigned );
int alloc_mem();
void adaug_prim_nod(unsigned &, unsigned &, int);
unsigned adaug_inainte_prim(unsigned , int);
unsigned adaug_dupa_ultim(unsigned , int);
void parcurg(unsigned);

int main()
{
unsigned prim, ultim, n;
init(prim, ultim);
cout<<"nr sunt:"<<endl; cout<<"nr="; cin>>n;
if(n!=0)
{ adaug_prim_nod(prim, ultim,n);
cout<<"nr="; cin>>n;
while(n!=0 && ! este_plina() )
{ if(n%2==0) prim = adaug_inainte_prim(prim, n);
else ultim= adaug_dupa_ultim(ultim, n);
cout<<"nr="; cin>>n;} }
if(!este_vida(prim))
{ cout<<"nr sunt:";
parcurg(prim);}
else cout<<"nu am nr"; }
void init(unsigned &prim, unsigned &ultim)
{ prim=ultim=NULL;
for(int k=1;k<=NMAX;k++)
liber[k]=1;}
int este_plina()
{ return nr_el==NMAX;}
int este_vida(unsigned prim)
{ return prim=NULL; }
int alloc_mem()
{ for(int k=1; !liber[k];k++)
liber[k]=0;nr_el++;}
void adaug_prim_nod(unsigned &prim,unsigned &ultim, int n)
{ prim=ultim=1;
liber[1]=0;
nr_el=1;
lista[prim].nr=n; lista[prim].urm=NULL;}
unsigned adaug_inainte_prim(unsigned prim, int n)
{ int p;
p=alloc_mem();
lista[p].nr=n;
lista[p].urm=prim;
return p;}
unsigned adaug_dupa_ultim(unsigned ultim, int n)
{ int p;
p = alloc_mem();
lista[p].nr=n;
lista[p].urm=NULL;
lista[ultim].urm=p;
return p;}
void parcurg(unsigned p)
{ cout<<lista[prim].nr<<'\t'<<";" ;
while(p!=NULL)
{ cout<<lista[p].nr<<" ";
p=lista[p].urm; }
}

well your first problems are you're using iostream.h... just use iostream.
Also you should either add using namespace std; or using std::cout; using std::cin; using std::endl; etc. Or use std::cout<<....

For the rest of the code: I don't get your question really, and it'd help if you'd post your code properly (spaces and tabs added where needed and put code brackets around it), cuz this is illegible.

Cheers!
