do I have to learn C language before starting for C++

Answer 1

You will understand this language better, but you don't have to. Sololearn is made for learning "from zero"

Answer 2

if you want you can, it's the advance version but yes starting from the beginning is good for better understanding.

Answer 3

No. Learn the good practices straight away.

Answer 4

Not necessarily. C++ is C with OOPs concept. Whatever you'll learn in C, you'll again learn in C++ added with OOPs concept. Both the languages are almost same.
And taking about the syntactical difference then one of the major difference is of cout as printf and cin as scanf.
Do not worry. Start with C++. Not a problem.

not necessary both are different language
