What is the difference between c and c++. if i know c, will it be hard to lean c++?

Explanation:

The difference between c and c++  are given below

(1) C does not support object oriented programming structure while c++ supports  object oriented programming structure.

(2) C does not support namespace concept while c++ support namespace concept

(3) C has a procedural language it means it follow top down approach while  C++ is object oriented it means it follow bottom up approach

(4) C does not support virtual function concept while C++ support  virtual function concept

( 5) The programming structure of c language is given below  

   #include<stdio.h> // header file

  void main()  //main method

{

//statement

}

Programming structure of C++

#include<iostream> // header file

 using namespace std;  // namespace

void main()  // main method

{

// statement

}

If anyone know C, will it be not hard to learn C++ because only the syntax will change but the logic of programming is not changed .The operator and most concept are similar in both the languages.
