I. Trace through the following loop, keeping track of the values of the variables.

int total=3;
double w=1.2;
do {
  if ( w > 3 ) total=6;
  w=w+0.5;
} while ( w < 3.5 );

II. Same thing...

int k=4;
double x=0;
while (k>2) {
  m=1;
  while (m<=2) {
    x=x+k;
    ++m;
  }
  k=k-1;
}

III. Show what gets displayed on the screen.

double BlackBox(double z, int n)
{
  cout << z << ", " << n+z << endl;
  return 3*z;
}

void main()
{
  int mm;
  mm=BlackBox( 1.0, 4);
  cout << mm;
}

IV. Show what gets displayed on the screen.

void proc1(int m) { cout << m << endl; }

void proc2()
{
  proc1(3);
  cout << "in proc2\n";
}

void main()
{
  cout << "Starting\n";
  proc2();
  proc1(5.2);
}
