Array of pointers and dinamically generated.

f should be a pointer to the start of an array of five (or whatever) pointers to ints. Thus, it needs to look like this:

int** f; // dynamic -- use new and delete or malloc and free
int* g[5]; // static -- prefered if you know that it'll be five since memory allocation is evil(tm)

int var1 = 12;
int var2 = 41;
int var3 = 913;
int var4 = 153;
int var5 = 1491;

f = new int*[5]; // C++ way
//f = (int**) malloc(5 * sizeof(int*)); // C way

for (int i=0; i<5; i++) {
  Serial.println(*f[i]);
  f[i]++;
}

Serial.println(var1);
Serial.println(var2);
Serial.println(var3);
Serial.println(var4);
Serial.println(var5);


delete f[]; // C++ way
//free(f); // C way I think
