need help with program

[cs1]

here is the question
1. read in a first name, last name and telephone number
and store these in the list.
2. a search function that reads in a first name and last
name and searches the list for the name and prints
the phone number if found.


and the is what i did

#include <iostream>
#include <cstring>
using namespace std;


struct pn {
	char fn[25];
    char ln[25];
	char pnbr[15];
      struct pn *next;
      };

int main() 
{
	char t1[64], t2[64],t3[64];
      struct pn *start=NULL, *p1,*p2,p3;

      
		  while(1){
			  cin >> t1;
			  if (strcmp(t1,"//")==0)break;
			  cin >> t2 >> t3;

            p1 = new struct pn;
            if (p1 == NULL ) {
                  cout << "memory error\n";
                  return 1;
                  }
			strcpy(p1 -> fn,t1);
           strcpy (p1 -> ln,t2);
			strcpy(p1 -> pnbr,t3);
			p1->next = start;
				start = p1;          
            }

		  while(1){
          cin >> t1;
		  if ( strcmp(t1,"//")==0)break;
		 
		  cin >> t2;
		  for (p1 = start; p1 != NULL; p1 = p1 -> next){
		  if ( strcmp(t1,p1 ->fn)==0)
			  (strcmp( t2,p1 ->ln)==0);
				  cout << "found b" << p1->pnbr << endl;
      break;
		  }
		  

		  {
			  if (p1== NULL) cout << "not found";
}
      
      


		  
		  return 0;
	  
			  }
}

so what my problem
there is no output


thanks

You could not possibly have output. Your code is not compileable. Fix the syntax errors.

Fix your indentation. It's a mess. Poorly indented code means you can't read it properly, and you'll make mistakes in editing it.

Watch your struct syntax. This is C++, not C. Read a C++ book on struct syntax if you aren't sure.

thanks
so all my code is wrong!!!!!!!!!! !!!!!!!1

hi,
when does this code come out of the loop?
[CODE=cpp]
while(1){
cin >> t1;
if (strcmp(t1,"//")==0)break ;
cin >> t2 >> t3;

p1 = new struct pn;
if (p1 == NULL ) {
cout << "memory error\n";
return 1;
}
strcpy(p1 -> fn,t1);
strcpy (p1 -> ln,t2);
strcpy(p1 -> pnbr,t3);
p1->next = start;
start = p1;
}[/CODE]

Its been a while since i touched pointers, but dosent start always gets pointed to the newly created struct?
which means that when u create a new node, the previous one is lost as a memory leak and you have no access to it anymore?
please correct me if i am wrong

[cs1]

ok
can i just know what the output ganna be
(just the output, i dont want the code)))
thanks again

[Shashi Sadasivan]

if you have written the code yourself, have you tried compiling it?

[cs1]

yeah i tried but the there is nothing

i don't want the program to work i just want to know how the program output should be . that's it.

thanks

Well, if the program doesn't work, then the output will be incorrect.

My guess is, you are looking for a cheap way out of doing an assignment. As you should know from reading our Posting Guidelines, we don't give away solutions to problems without the user having tried.

If you want the output of this program, you will have to correctly write the program first. Now, we are more than willing to help you - if you are willing to do some work and not demand the solution from us.

I understand that but I didn't say I want the answer I said i want to know how the out put should be like.

thanks again

There really doesn’t seem to be much to it. Then again, you’re the one with the question paper.

I would guess you have a menu system, someway of acknowledging or rejecting user input, and so on. It’s just simple console based output, so it’s not going to look like much more than ASCII...

[cs1]

thank you so much I'm working on it now.
