QUESTION 2 on ACTUAL TEST 3 will be very similar to

    #include <stdio.h>

      int f(int c, int b, int a, int d);
    int main() {
           int a = 1, b = 2, c=2 , d = 1;
           a = f(b,  f(a, c, b+c, d), a+c, d );
           printf("a=%d b=%d c=%d d=%d\n", a, b, c, d);
           system("pause");
           return 0;
      }
      int f(int c, int b, int a, int d) {
       int sum;
       b = a + c;
       sum = a + b + c;
       d = sum - b;
       printf("a=%d b=%d c=%d d=%d\n", a, b, c, d);
       if (sum > a*c)
         return a*c;
       if (sum <= b*c)
         return b*c;
       return a*b;
      }

The correct answers are:
a=4 b=5 c=1 d=5
a=3 b=5 c=2 d=5
a=6 b=2 c=2 d=1





AND FOR QUESTION 3 on ACTUAL TEST 3

#include <stdio.h>
int f(int *a, int c, int b, int *d);
int main(void) {
  int a=1, b=3, c=2, d= 1, e= 1;
  e =   f(&a, f(&b,a,e,&c), e, &d);
  printf("a= %d b= %d c= %d d=%d e=%d\n",a,b,c, d, e);
  system ("pause");
}
int f(int *a, int c, int b, int *d) {
  *a = *a - 1;
  c = c*2 + (*a);
  b = b - 1;
  *d = *a + 2;
  printf("a= %d, b= %d, c= %d d= %d\n", *a, b, c, *d);
  system("pause");
  return *d - *a + 1;
}

The correct answers are:
a=2 b=0 c=4 d=4
a=0 b=0 c=6 d=2
a=0 b=2 c=4 d=2 e=3
