Making an array element a reference to another variable

Projects Programming

I read it differently. I thought he is asking for an array of pointers to other variables. For example:

void setup() {
  //Initialize serial and wait for port to open:\
int *ptr[10];
int i;
int a, b, c;

Serial.begin(115200);
a = 5;
b = 10; 
c = 15;

ptr[0] = &a;
ptr[1] = &b;
ptr[2] = &c;
for (i = 0; i < 3; i++)
  Serial.println(*ptr[i]);
}
