The Correct Option is A

Solution and Explanation

First, sort the given data in ascending order: \[ 9, \, 10, \, 11, \, 11, \, 13, \, 14, \, 15, \, 17, \, 18, \, 69 \]
Since there are 10 numbers (even count), the median is the average of the 5th and 6th values: \[ \frac{13 + 14}{2} = 13.5. \] Final Answer: \[ \boxed{13.5} \]

What is the output of the following C code?

  void foo(int *p, int x) {
      *p = x;
  }

  void main() {
      int *z;
      int a = 20, b = 25;
      z = a;  // Incorrect: Should be z = a;
      foo(z, b);
      printf("%d", a);
  }

Issue: The statement z = a; is invalid because a is an integer, and z is a pointer.

Consider the following C code:

int main() {
    sum = 0;
    for (n = 1; n < 3; n++) {
        n++;
        sum += g(f(n));
    }
    printf("%d", sum);
}

int g(n) {
    return 10 + n;
}

int f(n) {
    return g(2 * n);
}
