Put it this way: every single MFE aside from like the top 10 in the country are simply a mish-mosh and retooling of existing courses from other departments with a year of Shreve thrown in and maybe some "get some third-rate employee out of a megafirm to dawdle and teach some tangentially related project course", and in turn, these programs charge thousands of dollars extra per semester when a student in a program with significant overlap can do just as well for themselves.
So unless you're going to Columbia/Berkeley/Baruch/Princeton/Stanford/MIT/NYU/UofC (not sure it has a quant program, since any engineer out of there with some financial background is about as good a quant as you'll get) or one of those other highly ranked programs, caveat emptor.
For instance, in Rutgers's MSMF, their one
C++ course covers the basics through linked lists. You want to be as good a quant programmer as anybody out of a non-top 10 MFE? Easy. Download Savitch's Absolute
C++, get Duffy's intro to
C++ for FEs, and if that's not enough yet, do some problems on ProjectEuler.net.
Want the math background that the quants have? Any MS in operations research/management science/statistics/applied math and you're more or less good to go. Anything finance related you can learn on the job--and odds are, you probably won't even realize you're picking up finance because it'll all be numbers and strings and vectors and matrices to you anyway.
Of course, once again, this doesn't apply to top 10 programs that have directors (or firm managers EG Sylvain Raynes) come in and teach their specialty just because they like to teach and placing you directly into fantastic job opportunities for crazy good pay, but
all of the other "quant" programs are nothing more than cash cows, with tons of bullshit for whatever gems of courses there are.
