Which is better for future? 

No one can predict the future in the technology domain; because things change here every single minute. As a software engineer / developer - you should *not* stick to any specific language; yet master one that you are currently working on. Let me make it very clear  - You need to be master of at least one and jack of several!  If you have concept of basic progrmmaing language; you should be able to get comfortable with any programming language, tool or framework within short time.

Start with any - and learn it with all the interest and try to be excellent. If you pick up .NET; don't hate Java and vice-versa. If your current job demands C# and ASP; learn it. If you are just starting out with a big IT company that has not told you which profile they will assign to you; it just doesn't matter.Company seeks engineers who are smart learner and can switch to any technology any time.

Difference between C and C++

1. C follows the procedural programming paradigm while C++ is a multi-paradigm language(procedural as well as object oriented)

2. C is a low-level language while C++ is a middle-level language (Relatively, Please see the discussion at the end of the post)

3. In case of C, the data is not secured while the data is secured(hidden) in C++

4. C++ allows the use of reference variables while C does not

5. The standard input & output functions differ in the two languages

6. We can use functions inside structures in C++ but not in C.

7. The NAMESPACE feature in C++ is absent in case of C

8. C++ supports function overloading while C does not

9. C is function-driven while C++ is object-driven

10. C uses the top-down approach while C++ uses the bottom-up approach
