Hello I should make a computer shop with c++ using classes. Please help me anyway you can.

Hello all; I am writing a tiny phone book program using classes.

using namespace std;
class phonebook{
public :
void add_new();

  private :
          char \*name;
          char \*family;
  };
  void phonebook::add\_new(){
       phonebook \*temp=new phonebook;
       cin >> temp->name;
       cin >> temp->family;
  }

int main(int argc, char *argv[])
{
phonebook::add_new();
system("PAUSE");
return EXIT_SUCCESS;
}

Any work I do; I can't get a name and family. my program should be dynamic. What should I do to get response? Thanks in advance...

Hello I want to program a phone book using two dimension pointers. Please help me with a simple example of string two dimensional pointer. Thanks in advance

Hello all and congratulate for new theme of site.

float f1,f2;
bool b;
float f1 = 10.0;

b = f1 == (f2 * 3.0);

WHY always b is 0 (false). Really aren't f1 and f2 equal? If it is, why? THankS in AdVanCE. . .

Hello Ash; I wrote these codes you say me. but it doesn't work correctly. It stop in another position that there is no wall and sometime it pass a wall and stop on the next one. These code are right, but I can't write them in its own place. Please help me by writing codes if it is possible for you.
