Bc++ is not a recognized programming language. It seems like there might be some confusion between two different languages: B and C++. B is an early programming language, developed at Bell Labs in 1969, which served as the precursor to the widely used C language. On the other hand, C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language. It has imperative, object-oriented and generic programming features while also providing facilities for low-level memory manipulation. If you're referring to Borland C++, it's a compiler for the aforementioned C++ coding language developed by Borland International Inc., known for its Integrated Development Environment (IDE).

First 20 minutes

General Bc++ app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Bc++ application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you define the main function in Bc++?

The main function in Bc++ is defined as 'int main()'. It is the entry point of the program and where the execution of the program begins.

What are the basic data types in Bc++?

The basic data types in Bc++ are int, char, float, and double.

Describe the difference between a class and a structure in Bc++.

In Bc++, a class and a structure are almost similar. The only difference is that members of a structure are public by default, while members of a class are private by default.

How would you use pointers in Bc++?

Pointers in Bc++ are used to store the address of a variable. They are declared using the '*' operator and can be used to access the variable directly.

What are the different types of loops in Bc++?

The different types of loops in Bc++ are for loop, while loop, and do-while loop.

Next 20 minutes

Specific Bc++ development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

Describe the difference between pass by value and pass by reference in Bc++.

In pass by value, a copy of the variable is passed to the function, so changes made inside the function do not affect the original variable. In pass by reference, the address of the variable is passed to the function, so changes made inside the function affect the original variable.

How would you handle exceptions in Bc++?

Exceptions in Bc++ are handled using the try, catch, and throw keywords. The code that might throw an exception is put inside a try block, and the exceptions are caught in the catch block.

What are the different types of inheritance in Bc++?

The different types of inheritance in Bc++ are single inheritance, multiple inheritance, multilevel inheritance, hierarchical inheritance, and hybrid inheritance.

Describe the difference between overloading and overriding in Bc++.

Overloading is when two or more functions in the same scope have the same name but different parameters. Overriding is when a derived class has a definition for one of the member functions of the base class.

How would you implement polymorphism in Bc++?

Polymorphism in Bc++ can be implemented using function overloading, operator overloading, and virtual functions.

Oops! Something went wrong while submitting the form.

At this point, a skilled Bc++ engineer should demonstrate strong problem-solving abilities, proficiency in Bc++ programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Bc++.

What does the following simple Bc++ code do?
int main() {
   int a = 10;
   int b = 20;
   int sum = a + b;
   cout << sum;
   return 0;
}
This code declares two integer variables 'a' and 'b', assigns them the values 10 and 20 respectively, adds them together, assigns the result to the variable 'sum', and then outputs the sum, which is 30.
What will be the output of the following Bc++ code?
int main() {
   for(int i = 1; i <= 5; i++) {
      cout << i << ' ';
   }
   return 0;
}
This code will output the numbers 1 through 5, each followed by a space. So the output will be '1 2 3 4 5 '.
What does the following Bc++ code do that deals with arrays?
int main() {
   int arr[5] = {1, 2, 3, 4, 5};
   for(int i = 0; i < 5; i++) {
      cout << arr[i] << ' ';
   }
   return 0;
}
This code declares an array of five integers, assigns the values 1 through 5 to the elements of the array, and then outputs these values, each followed by a space. So the output will be '1 2 3 4 5 '.
What does the following Bc++ code do that deals with threading?
#include 
void foo() {
   cout << 'Hello World';
}
int main() {
   thread t1(foo);
   t1.join();
   return 0;
}
This code includes the thread library, defines a function 'foo' that outputs 'Hello World', creates a new thread 't1' that runs this function, waits for this thread to finish, and then returns 0. So the output will be 'Hello World'.

Wrap-up questions

Final candidate for Bc++ Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle Bc++ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of constructors in Bc++?

The different types of constructors in Bc++ are default constructor, parameterized constructor, copy constructor, and dynamic constructor.

Describe the difference between a virtual function and a pure virtual function in Bc++.

A virtual function has a definition in the base class and can be overridden in the derived class. A pure virtual function does not have a definition in the base class and must be overridden in the derived class.

How would you use templates in Bc++?

Templates in Bc++ are used to create generic functions or classes. They allow the same function or class to operate on different data types.
