ROUND 1 :- TCS Technical  Interview

1.Tell me about yourself.

I mentioned on my Resume JAVA., C, and C++ so I got mainly questions in JAVA.

2. Difference between C and C++.

C C++
C does not support OOPS concept C++ supports OOPS concepts like object, inheritance, etc
C is a procedural language, where each line of code is an instruction for the compiler. C++ is a Hybrid language having a combination of both object oriented language and proecdural programming language.
C has a predefined function support only in the form of header files, and therefore the names within the file or program cannot be duplicated. C++ has namespace feature which enables it to have same names for functions or variables.
C supports 32 keywords C++ supports the same 32 keywords as C, along with that it also supports 20 exclusive keywords.
C has no support for excerptions, and any runtime error can shutdown the program immediately. C++ has try, throe and catch keywords, using which exceptions can be handled, and abnormal terminations can be avoided.

3. What are the OOPS concepts?

There 4 basic pillars in OOPS:

  • Encapsulation
  • Inheritance
