Using code inside sizeof can lead to unexpected behavior; sizeof evaluates at compile time, not runtime.
sizeof is evaluated at compile time, so any code inside it must not have side effects.
Example: sizeof(1 + 2) evaluates to sizeof(int), not the result of the expression.
Using function calls inside sizeof is allowed, but the function must not have side effects.
Example: sizeof(someFunction()) is valid if someFuncti...
Swapping bits in a byte involves exchanging the positions of bits within an 8-bit binary number.
A byte consists of 8 bits, indexed from 0 to 7.
To swap bits, you can exchange pairs: (0, 7), (1, 6), (2, 5), (3, 4).
Example: For byte 10110010, swapping gives 01011001.
Use bitwise operations: AND, OR, and XOR to manipulate bits efficiently.
In programming, you can use masks to isolate and swap bits.
Expected CTC should be based on industry standards, experience, skills, and location.
Research industry standards for Embedded Software Engineers in your location.
Consider your level of experience and skills - more experience and specialized skills may command a higher salary.

This program demonstrates how to manipulate arrays of strings in embedded software.
Use arrays to store multiple strings, e.g., char *names[] = {'Alice', 'Bob', 'Charlie'};
Access elements using indices, e.g., printf('%s', names[0]); // Outputs 'Alice'
Iterate through the array using loops, e.g., for(int i = 0; i < 3; i++) { printf('%s', names[i]); }
Consider memory management, especially in embedded systems where ...
Find the frequency of each character in a given string.
Iterate through the string and count the occurrences of each character
Store the frequencies in a map or array

Count the number of characters in the word 'Mirafra' using a simple coding approach.
Use the built-in function 'len()' in Python to count characters.
Example: len('Mirafra') returns 7.
Iterate through the string and count manually if needed.
Example: Initialize a counter and loop through each character.
Retrieve the 4th highest salary from an Employee table using SQL queries.
Use the 'DISTINCT' keyword to avoid duplicate salaries: SELECT DISTINCT salary FROM Employee.
Utilize 'ORDER BY' to sort salaries in descending order: SELECT DISTINCT salary FROM Employee ORDER BY salary DESC.
Use 'LIMIT' with an offset to get the 4th highest salary: SELECT DISTINCT salary FROM Employee ORDER BY salary DESC LIMIT 1 OFFSET 3.

Understanding prefix and postfix expressions is crucial for evaluating expressions in programming languages and data structures.
Prefix expression (Polish notation) places the operator before its operands. Example: + 3 4 evaluates to 7.
Postfix expression (Reverse Polish notation) places the operator after its operands. Example: 3 4 + evaluates to 7.
To evaluate a prefix expression, read from right to left using a st...

- Q1. How does twisted cable work? How to see CAN voltage levels on Oscilloscope?
- Ans.
Twisted cables reduce electromagnetic interference and CAN voltage levels can be observed using an oscilloscope.
Twisted cables consist of pairs of wires twisted together to cancel out electromagnetic interference.
The twisting helps maintain a consistent impedance, reducing signal degradation over distance.
To see CAN voltage levels, connect the oscilloscope probes to the CAN High and CAN Low lines.
Set the oscilloscope t...

- Q1. What is oops concept example with each one
- Ans.
Object-oriented programming concepts include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: bundling data and methods that operate on the data into a single unit (class). Example: class Car with properties like make, model, and methods like start(), stop().
Inheritance: creating new classes based on existing classes, inheriting their attributes and methods. Example: class SUV inheriting from cl...
- Q2. What is data structures and types with examples of all types
- Ans.
Data structures are ways of organizing and storing data in a computer so that it can be accessed and used efficiently.
Types of data structures include arrays, linked lists, stacks, queues, trees, graphs, and hash tables.
Arrays are a collection of elements stored in contiguous memory locations, accessed using an index.
Linked lists are a series of nodes where each node contains data and a reference to the next node.

- Q3. What is class and objects with example and code
- Ans.
A class is a blueprint for creating objects in object-oriented programming. Objects are instances of classes.
A class defines the properties and behaviors of objects. For example, a 'Car' class may have properties like 'color' and 'model', and behaviors like 'drive' and 'stop'.
An object is an instance of a class. For example, 'myCar' can be an object of the 'Car' class with specific values for 'color' and 'model'.

- Q4. What is virutal function and staic functions
- Ans.
Virtual functions are functions in a base class that are overridden in derived classes, while static functions belong to the class itself rather than instances.
Virtual functions allow for dynamic binding and polymorphism in object-oriented programming.
Static functions are associated with the class itself and can be called without creating an instance of the class.
Example: virtual void display() = 0; // pure virtual fun...

- Q2. Swap the number from 0x12345 to 0x54321
- Ans.
To swap the hexadecimal number 0x12345 to 0x54321, we can use bitwise operations or simple arithmetic.
Use bitwise XOR to swap without a temporary variable: a = a ^ b; b = a ^ b; a = a ^ b.
Convert hex to decimal: 0x12345 = 74565, 0x54321 = 340761.
Perform the swap: a = 0x12345, b = 0x54321; after swap, a = 0x54321, b = 0x12345.
