What is the difference between C and C++. If I know C, will it be hard to lean C++?

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 / / header file

void main () / /main method

{

//statement

}

Programming structure of C++

#include / / 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.
