Ejemplos de Programas con Punteros

PROGRAMA #1

#include <iostream>
using namespace std;
 
int main() {
   char cadena1[] = "Cadena 1";
   char *cadena2 = "Cadena 2";
 
   cout << cadena1 << endl;
   cout << cadena2 << endl; 

   //cadena1++; // Ilegal, cadena1 es constante 
   cadena2++; // Legal, cadena2 es un puntero 

   cout << cadena1 << endl; 
   cout << cadena2 << endl;
 
   cout << cadena1[1] << endl;
   cout << cadena2[0] << endl;
 
   cout << cadena1 + 2 << endl; 
   cout << cadena2 + 1 << endl;
 
   cout << *(cadena1 + 2) << endl; 
   cout << *(cadena2 + 1) << endl; 
   
   return 0;
}

PROGRAMA #2

#include <iostream>
using namespace std;
 
struct stEstructura {
   int a, b; 
} estructura, *e;
 
int main() { 
   estructura.a = 10;
   estructura.b = 32;
   e = &estructura;
 
   cout << "puntero" << endl;
   cout << e->a << endl;
   cout << e->b << endl;
   cout << "objeto" << endl;
   cout << estructura.a << endl; 
   cout << estructura.b << endl; 

   return 0;
