C or C++ the Eternal Question or Perhaps Not for a NOVICE

I am a Financial Professional w/Engineering degree, MBA, CFA
I work in the Derivatives/Securities industry
Most programs at our firms (esp. for Quant.Analysis Trading) are done in C/C++

Which language do YOU guys Suggest I learn.
Yes I have read previous posts from others suggesting that C is more systems-level oriented. More specifically, are all concepts/syntax easily transferable to C++ once learned ?
also, does the C++ envirionment leave out essential UNIX/System level concepts and knowledge. I might add that I will be dealing with large batches of transaction data and data feeds in simple text or delim format esp.suited for Unix os. Stock market data is extensive.

I might add that I learn very quickly and complexity is not an issue at the risk of sounding im-modest. and I am not interested in becoming a Guru, simply to get THE JOB I WANT.

Thanks guys in advance, please do not be arrogant.

learn c or c++, c lends itself to c++ pretty easily, but i think it's better to learn c++ first....and you won't miss out on unix, c/c++ is system independent, you can code for whatever system you like. You won't miss a thing.
