10+ TÜV NORD Interview Questions and Answers

Call by value passes a copy of the value, while call by reference passes a reference to the original value.

• Call by value creates a new copy of the value being passed.

• Call by reference passes a reference to the original value.

• Changes made to the parameter in call by value do not affect the original value.

• Changes made to the parameter in call by reference affect the original value.

A program to print random token numbers.

• Generate random numbers using a random number generator

• Convert the numbers to strings and store them in an array

• Print the token numbers from the array

The probability of getting heads or tails when flipping a coin is 50% for each outcome.

• When flipping a fair coin, there are only two possible outcomes: heads or tails.

• Since the coin has no bias, the probability of getting heads is 50% and the probability of getting tails is also 50%.

• This is because there is an equal chance for the coin to land on either side.

• The probability can be calculated by dividing the number of favorable outcomes (1 for heads or 1 for tails) by the tota...read more

Tuples and lists are data structures in Python used to store multiple items.

• Tuples are immutable and ordered collections of elements.

• Lists are mutable and ordered collections of elements.

• Both can store different data types.

• Tuples are defined using parentheses, while lists use square brackets.

• Example: tuple = (1, 'a', True), list = [1, 'a', True]

The code is a software program that performs a specific function.

• The code is written in a specific programming language.

• It may contain functions, classes, or modules.

• The code may interact with databases or external APIs.

• It could be part of a larger software system or application.

• The code may have been written by multiple developers.

• It may include comments or documentation to explain its purpose.

A while loop is a control flow statement that allows code to be executed repeatedly based on a given condition.

• While loop continues to execute a block of code as long as the specified condition is true

• The condition is evaluated before each iteration of the loop

• Example: while (x < 5) { // code to be executed }

4 types of piler in oops are JIT compiler, AOT compiler, JIT interpreter, and AOT interpreter.

• JIT compiler - Just-In-Time compiler that compiles code during runtime for improved performance.

• AOT compiler - Ahead-Of-Time compiler that compiles code before runtime for faster execution.

• JIT interpreter - Just-In-Time interpreter that interprets code during runtime without prior compilation.

• AOT interpreter - Ahead-Of-Time interpreter that interprets code before runtime for immediat...read more

Java is a high-level programming language known for its platform independence and object-oriented features.

• Java is a class-based, object-oriented programming language.

• It is designed to have as few implementation dependencies as possible, making it highly portable.

• Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM).

Insertion sort is a simple sorting algorithm that builds the final sorted array one item at a time.

• Start with the second element and compare it with the first element, swap if necessary

• Move to the third element and compare it with the first and second elements, swap if necessary

• Continue this process until the entire array is sorted

• Time complexity is O(n^2)
