hello
the problem is like this i have a linked list, i need to delete the nods that have info 'a'

the program is this one


Code:
#include <iostream>

using namespace std;

struct nod
{
	char info;
	nod *urm;//urm is pointer to the next node
};nod *prim,*ultim;//prim remembers the first node, ultim remembers the
                                 last one   

void adaugare (char a);
void verificare();
void primnod();
int main()
{
	int n;//size of list
	char k; //info
	cout<<"cate elemente vrei sa adaugi in lista? ";
	cin>>n;    
	primnod();//the function that declares the frist node
	for(int i=2;i<=n;i++)
	{	
                    cout<<"dati valoarea pt elementul al"<<i<<"-lea ";
	    cin>>k;
	    adaugare(k);
	}
	nod *x= new nod;

	verificare();
	x=prim;
	for(x=prim;x<=ultim;x=x->urm)
	{
		cout<<x->info<<" ";
		if(x->urm==NULL)
		{cout<<endl;
		 break;
		}
	}
	cout<<"merge";

	return 0;
}
void primnod()
{
	nod *p=new nod;
	cout<<"introduceti valoarea primului nod ";
	cin>>p->info;
	prim=ultim=p;
	p->urm=NULL;
	

}
void adaugare(char a)
{
	nod *p= new nod;
	p->info= a;
	ultim->urm=p;
	ultim=p;
	p->urm=NULL;
	
}
void verificare()
{	nod *x=new nod;
	nod *q=new nod;
	x=prim;
	q=prim;
	while(prim->info=='a')
	{
		nod *p;
		p=prim;
		prim=p->urm;
		delete p;
	}

	

	
	
	while(q->urm!=NULL)
	{	
		
		if(q->urm->info=='a')
		{
			nod *i=new nod;
			
			i=q->urm;
			while(i->info='a')
			{
			 nod *t= new nod;
			 t=i;
			 i=t->urm;
			delete t;
			}
			q->urm=i->urm;
			delete i;

		}
		q->urm=q->urm->urm;
	
	}


	
}
i want u to look at the verificare function and after the verification if the first node is a...

exactly this part
Code:
	while(q->urm!=NULL)
	{	
		
		if(q->urm->info=='a')
		{
			nod *i=new nod;
			
			i=q->urm;
			while(i->info='a')
			{
			 nod *t= new nod;
			 t=i;
			 i=t->urm;
			delete t;
			}
			q->urm=i->urm;
			delete i;

		}
		q->urm=q->urm->urm;
	
	}
i thinked like this, i positioned with q before the node with 'a' info i created a pointer to q->urm then i entered in a while loop and created a pointer to start delete the nodes with a...if they are more in line...

please tell me what is wrong, i'm sorry for my bad format, this is my first post on this forum...
