HEG Purchase Officer Interview Questions and Answers

UDP is preferred over TCP in this project due to its low latency and lightweight nature.

• UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.

• UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.

• UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...read more

To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.

• Create a mask with the 7th bit set to 0 and all other bits set to 1

• Perform a bitwise AND operation between the register and the mask

• Store the result back in the register

Phases of compiler include lexical analysis, syntax analysis, semantic analysis, code generation, and optimization.

• Lexical analysis: breaking down input into tokens

• Syntax analysis: checking if tokens form valid syntax

• Semantic analysis: checking if syntax is semantically correct

• Code generation: generating machine code from input

• Optimization: improving generated code performance

C is preferred over C++ for certain applications due to its simplicity and efficiency.

• C is a simpler language compared to C++ and has a smaller runtime footprint.

• C is often used for low-level programming, embedded systems, and operating systems.

• C allows for more control over memory management and can be faster in certain scenarios.

• C++ introduces additional features like object-oriented programming and templates, which

Classes are blueprints for creating objects, while structures are similar but with different default access levels.

• Classes and structures are used to define the structure and behavior of objects in object-oriented programming.

• Classes are reference types and are allocated on the heap, while structures are value types and are allocated on the stack.

• Memory allocation for classes is managed by garbage collection, while mem...read more
