Recursion

Consider the following program:

int f(int *p, int n)
{
    if (n <= 1) return 0;
    else return max(f(p+1,n-1),p[0]-p[1]);
}
int main()
{
    int a[] = {3,5,2,6,4};
    printf("%d", f(a,5));
}

*Note*: max(x,y) returns the maximum of x and y. The value printed by this program is ________.

Consider the following function

double f(double x){
    if( abs(x*x - 3) < 0.01) return x;
    else return f(x/2 + 1.5/x);
}

Give a value q (to 2 decimals) such that f(q) will return q: _____.

Consider the C function given below.

int f(int j)
{
    static int i = 50;
    int k;
    if (i == j)
    {
        printf("something");
        k = f(i);
        return 0;
    }
    else return 0;
}

Which one of the following is TRUE?
