Is there a difference between the "if" tests shown below? If so, explain why
one might be preferred over the other.
if (*p == MAX_VALUE)
return -1;
if (MAX_VALUE == *p)
return -1;

For Master, you can find a technician job (easy). But you will need to pay
your tuition and cover your own expense.
For Ph.D., you can find a postdoc (easy), and anything beyound there is up
to your luck, and ability of course. You can normally get some kind of
financial aid.

MAX_VALUE不能作lvalue，compiler可以帮助programmer避免把==写成=

if (MAX_VALUE == *p) 误写成 if (MAX_VALUE = *p)编译器会报错。MAX_VALUE不能作
lvalue。
if (*p == MAX_VALUE) 误写成 if (*p = MAX_VALUE)编译器不会报错。

Both are okay.
*p == MAX_VALUE is better for the long run since it is more intuitive
and more easily readable. Just need to pay attention (easily trainable
habbit) when writing ==. It is a fairly easy bug to discover even if
you make a mistake as well.
ease of reading > ease of debugging

这个也分情况说把, 美国有好多地方生物教育都是精英教育, mit生物得中国学生
就比ee/cs得都少, 还有像rockefeller/UCSF那样得地方. 当然如果想当民工，
肯定是生物比较容易一些
