Consider the following ANSI C program

#include <stdio.h>

int foo(int x, int y, int q)

{

if ((x <= 0 && (y <= 0))

return q;

if (x <= 0)

return foo(x, y - q, q);

if (y <= 0)

return foo(x - q, y, q);

return foo (x, y - q, q) + foo(x - q, y, q);

}

int main()
(

int r = foo(15, 15, 10);

printf("%d", r);

return 0;

}

The output of the program upon execution is ________ 

Consider the following ANSI C program.

#include <stdio.h>

int main( ) {

int i, j, count;

count = 0;

i = 0;

for (j = -3; j <= 3; j++)  {

if ((j >= 0) && (i++))

count = count + j;

}

count = count + i;

printf("%d", count);

return 0;

}

Which one of the following options is correct?

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 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 ________.
