Using references as an array...

Hi,

void myFunction(char &myArray, unsigned int arraySize){
     for(unsigned int i=0;i<arraySize;i++)
          cout<<myArray[i];
     cout<<endl;
}

Produces a "subscript requires array or pointer type"? I'd prefer to stick with references if possible, and I'm going to be passing in things like:

char *myArray=new char[20];
myFunction(myArray[10], 2);

so will I still be able to use references in this manner?

Thanks,
Uni

I'm confused at what you're trying to do :

        char *myArray=new char[20];

creates an array of 20 chars.

        myFunction(myArray[10], 2);

passes the 11-th character from that array.

        void myFunction(char &myArray, unsigned int arraySize){

accepts that 11-th character by reference.

        cout<<myArray[i];

but then you try to treat the character as an array ...

Did you mean this :


void myFunction(char *myArray, unsigned int arraySize){
     for (unsigned int i = 0; i < arraySize; i++)
          cout << myArray[i];
     cout << endl;
}
 
char *myArray = new char[20];
myFunction(&(myArray[10]), 2);

Actually... yep, that's it... I'm getting a little confused with how references are used... My bad.
