Consider the following ANSI C function:

int SimpleFunction (int y[], int n, int x)

{

int total = y[0], loopIndex;

for (loopIndex = 1; loopIndex <= n - 1; loopIndex++)

total = x * total + y[loopIndex];

return total :

}

Let Z be an array of 10 elements with Z[i] = 1, for all i such that 0 ≤ i ≤ 9. The value returned by SimpleFunction (Z, 10, 2) is ______

Consider the following C functions.

int fun1 (int n) {
     static int i = 0;
     if (n > 0) {
            ++i;
            fun1(n-1);
     }
     return (i);
}

int fun2 (int n) {
     static int i = 0;
     if (n > 0) {
            i = i + fun1 (n);
            fun2(n-1);
     }
     return (i);
}

The return value of fun2 (5) is _______.

Consider the following C functions.

int tob(int b, int* arr) {
     int i;
     for (i=0; b>0; i++) {
           if (b%2) arr[i] = 1;
           else arr[i]=0;
           b = b/2;
    }
    return (i);
}

int pp(int a, int b) {
     int arr[20];
     int i, tot = 1, ex, len;
     ex = a;
     len = tob (b, arr);
     for (i=0;  i < len; i++) {
           if (arr[i] ==1)
              tot = tot * ex;
           ex = ex * ex;
    }
    return (tot);
}

The value returned by pp (3, 4) is ________.

Consider the following C code. Assume that unsigned long int type length is 64 bits.

unsigned long int fun(unsigned long int n){
     unsigned long int i, j = 0, sum = 0;
     for (i = n; i > 1; i = i/2) j++;
     for ( ; j > 1; j = j/2) sum++;
     return(sum);
}

The value returned when we call fun with the input $${2^{40}}$$ is
