USTGlobal Technical interview Questions

UST global interview questions for learn and practice

1 What is C++?
C++ maintains almost all aspects of the C language, while simplifying memory management and adding several features - including a new datatype known as a class (you will learn more about these later) - to allow object-oriented programming. C++ maintains the features of C which allowed for low-level memory access but also gives the programmer new tools to simplify memory management. C++ is a powerful general-purpose programming language. It can be used to create small programs or large applications.

 

2.Can you Mention some Application of C/C++?

 

3. What is the difference between C and C++?

 

4.What is the advantage of OOP?

**Simplicity

**modularity:

**modifiability

**extensibility

**maintainability

**re-usability

 

4. Can you Explain- What is modularity?

 

5. How do you do dynamic memory allocation in C applications? 

In C, malloc, calloc and realloc are used to allocate memory dynamically. In C++, new(),is usually used to allocate objects.

 

6.List advantages and disadvantages of dynamic memory allocation vs. static memory allocation.?

 

7.What is Java?
Java is an object-oriented programming language developed initially by James Gosling and colleagues at Sun Microsystems. The language, initially called Oak (named after the oak trees outside Gosling's office),was intended to replace C++, although the feature set better resembles that of Objective C. Java should not be confused with JavaScript, which shares only the name and a similar C-like syntax. Sun Microsystems currently maintains and updates Java regularly. 

 

8.Can you have virtual functions in Java?

 

9. What is a transient variable in Java?

 

10.What is thread?
A thread is an independent path of execution in a system.

11.What is multi-threading?
