Which one should we learn first, C or C++?

[debasis]

I want to learn C and C++. I read somewhere that C is nothing but C++ but low version, so we can directly learn C++ without learning C.
Please give me your advice should I learn C++ first.
Also please suggest me any software to write C or C++ that I shall be able to download from internet freely.

First one has to learn C then C++ one can't jump directly to C++ without learning C if you have knowledge Of C then you can Jump directly to C++
Thank You.
