[avr-gcc-list] How to pass an array to founction

[Domenico Formenton]

Hi,
I would like to pass an array of char to a function and, in the
function, insert some data into the array, so that it can read the data
in the calling function. Something like:

char arr[20];
compute(arr);
....
char c;
c = arr[0];  // Must return 'A'!!!!!

void compute (char a[]) {
    a[0] = 'A';
   ...
   ...
}

What should I modify it to work as I want?

thank you very much.

Domenico
