1) Do the conversion.  Show your work.  No credit if you don't show some work.

1a) Convert 87 decimal to binary.






1b) Convert 87 decimal to hex.






1c) Convert 1010101 binary to hex.






1d) Convert 1010101 binary to decimal.







2) Be the computer.  For each, keep track of the values of all the variables
   as the code runs - as we did in class.  


2a) basic arithmetic.

// code
int x = 3, y = 2;
float z = x * y;
x = x - x * y;
y = y * y + 14;
y = (x + y) % 7;
z = z / 4.0;

// variable values.
//
// x: 
//
// y: 
//
// z: 
//








2b) Boolean logic, conditionals.

// code
int x = 18;
float f = 1.5;
if (x > 10 || f <= 0) {
   if (x >= 19 ) x = x / 5;
   else x = 2 - x;
   f = f / f;
}
else {
   if (x <= 3.0) x = f * x;
   else x = x - f;
   f = f * f;
}
x = (f < x && x >= f) || (f > x || x > f);

// variable values.
//
// x:
//
// f:
//









2c) Loops.

// code
int i;
int total=0;
for(i=1; i < 12; i += 2) {
  total = total + i;
}

// variable values.
//
// i:
//
// total:
//
