No... Don't learn C first... It will only confuse you.. more and you will mainly forget a lot. Learn basic C++ first (Which includes all of the topics classes, variables etc.) THEN learn basic C.
if you start learning C first then you will be writing stuff like uint32_t and being like 'WTF MEZ L333TZZ CODEZ DOESNTZ COMPILZ HELLPZ'
Now, may I pose a question... How long have you been doing C++ for? You obviously have no idea what you're talking about nor should make a thread claiming that your the l33tness at C++ and everyone should learn the harder way and end up quiting C++ within a week since C confused you to much..
