When possible, SHOW YOUR WORK.  Also, YOU MAY NOT USE A COMPILER OR ANY OTHER MATERIALS (except a pen and your brain).

0.  Write your name on the top-right corner.  No name, no grade, no exceptions.

1.  Write the API's for apvector and apmatrix.

2.  Determine precisely what the following program will print out when executed.

#include <stdio.h>
#include <iostream.h>

int g2(int y, double x, int& z)
{
 if (z) z++;
 x = y / (--z);
 cout << "g2: " << x << y << z << endl;
 return x;
}

int g1(int x, int& y, double& z)
{
 while (z = g2(z,y,x))
  x++;
 cout << "g1: " << x << y << z << endl;
 return x + y + z;
}

void part1()
{
 int x,z;
 double y;

 x = (y = 2.5) > (z = 2.9);
 z += 0.1;

 x = g1(x,z,y);

 cout << "main: " << x << y << z << endl;
}

void part2()
{
 int a,b;
 a = b = 12;
    for (a = 3; a < a+1; a++)
    {
      if ((a % 2) * a >= a - 4)
       continue;
      if (!((b += a) % 4))
       break;
    }
 cout << "part2: " << a << b << endl;
}

void main()
{
 part1();
 part2();
 getchar();
}
