Thread: C++ code question

I need to remove an existing structure from a linked list of structures and the argument passed to remove() should be the address of the structure preceding the record to be removed....is this a good start?

Code:

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

struct Info
{
 string name;
 string teleno;
 };
 
 void remove(Info*);
  
int main()
{
 Info * val;
 int i;
 
 cout<< "Enter a name:  ";
  cin>> val -> name;
 cout<< "Enter a telephone number:  ";
  cin>> val -> teleno;

return 0;  
}

It is ok as a start. You need to have your val point actually point to something, although I don't know why it needs to be a pointer.

You also don't have a linked list. Were you supposed to make the structure a linked list node?

You'll also probably have to walk through the list to find the element to delete.

It's hard to say whether that really is a good start because I don't know the rest of the context.

does this look a bit better?

Code:

struct Info
{
   string name;
   string teleno;
   Info * next;
};
 
 void remove(Info*);
 
int main()
{

Info num;
num = remove();
cout << "The name is:  " << num.name
cout << "The telephone number is:  " << num.teleno << endl;

return 0; 
}

Info looks more like a list now, but I'm not sure what you are trying to do inside your main function.

Do you have a written out (in words) description of everything you plan on doing?
