Qualcomm Interim Engineering Intern Interview Questions and Answers

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

Design logical circuits for arithmetic circuits in a blackbox.

• Understand the functionality of the arithmetic circuits in the blackbox.

• Identify the inputs and outputs of the blackbox.

• Design logical circuits using logic gates to replicate the arithmetic operations.

• Test the logical circuits to ensure they produce the same outputs as the arithmetic circuits.

Recursion in embedded C-code allows a function to call itself, useful for repetitive tasks or complex algorithms.

• Ensure proper base case to avoid infinite recursion

• Use stack space efficiently as embedded systems have limited resources

• Avoid recursive functions with deep call stacks to prevent stack overflow

• Example: Recursive function to calculate factorial of a number
