10.8

Give the output of the following program written in C syntax using the four parameter passing methods discussed in section 10.3


int i
int a[2];


void p(int x, int y)
{   x++;
     i++;
     y++;
}
main()
{   a[0] = 1;
     a[1] = 1;
     i = 0;
     p(a[i],a[i]);
     printf("%d\n",a[0]);
     printf("%d\n",a[1]);
     return 0;
}


It prints:
1
1


it doesn't increment the values as one might think because they're passed by value, not by reference
