Pointer arrays

Why can't I input into the pointer array?

#include <iostream>
#include <cstdlib>
#include <cctype>

int main(){
char *g[5];

for (int i=0; i<5; i++)
cin>> g[i];

for (int i=0; i<5; i++)
cout<< g[i]<< endl;

system("PAUSE");
return 0;
}

Hi,
Pointers and arrays always mess with me. Here is how I modified your program to work. I would give an explanation but I would probably describe it incorrectly. Some of the gurus on this site will do a much better job than I. :-)

Anyhow, this code works....

Code:

---

#include <iostream>
#include <cstdlib>
#include <cctype>

int main(){
  char g[5];
  char  *p = g;  //this creates a pointer to g...I think
  for (int i=0; i<5; i++)
    cin >> p[i]; //this loads input into address
  for (int i=0; i<5; i++)
    cout<< g[i]<< endl;
  system("PAUSE");
  return 0;
}

Pointer array is an array to store pointers.

Yep, you're unlikely to receive a pointer as input from the user. And if that should be an array of strings: you don't allocate memory from them.

For an array of strings you'd better write:

Code:

---

#include <string>
using namespace std;

//...
string ar[5];

Ok, thank you very much! All of you.
