1 point per little problem, then rescale so it's worth 8 points.

Advice - do problem 3, then 2, then 1.

1. For each, give the value(s) printed.

1a) 
printf("%c", (103 >> 2) << 2 );


1b)
printf("%x", (0xfa80 | 0x7) > 0 );


1c)
for(char c='0'; isdigit(c); c += 2) {
  printf("%c", c++);
}


1d)
int x[5] = {5, 4, 3, 2, 1};
int * y = &x; x /= 2;
y++; y[1] = 3;
int * z = y++;
printf("%i, %i, %i", x[0], y, z);


1e)
char s[10] = "abcde"; char *z = s;
for(; z; ) {
  if (z[0] == s[0]) z++;
  else z += 2;
  *z = toupper(*z);
}
printf("%c, %s\n", *z, s);


1f)
int x = 42;
while (x > 0) {
  printf("%i", x % 2);
  x /= 2;
}


1g)
printf("%i, %i, %f\n", 17 / 3, 17 % 3, 17 / 3.0);


1h)
int x = 1;
if ((x = 0) || (x++)) x++;
printf("%i", x);


2) Give the min, max, and # bytes for each of the following data types

2a) unsigned char

2c) int

2e) short

2h) unsigned long int

2i) float

2j) double


3) Give an extremely short phrase (at most 10 words) describing what each keyword does

3a) static, for local variable


3c) const


3e) #define


3f) sizeof


3g) extern, for global variable


3i) typedef


3o) continue
