9. Writing and tracing code
10. Passing arguments: Pass by value and pass by reference
public static void main(String[] args) {
int [] a = { 64 };
int [] b = {32};
int c = 88;
int d = 77;
confused ( a, c, b, d);
System.out.print(a[0] + "," + b[0] + "," + c + "," + d);
// a[0] = _____, b[0] = _____, c = _____, d = _____
}
public static void confused(int [] c, int d, int [] a, int b) {
a[0] = 1;
c[0] = 2;
d = a[0]*d + c[0];
b = d + c[0]*d;
}
