0 is the answer
The division of 5/9 is 0.5
Then 0.5*(t-32) is -31.5
So roundup of this is 0.

Ques:- Hello Experts, What is the difference between move and move corresponding exactly? please post me asap

Asked In :- Data Patterns,

Right Answer:
The difference between `MOVE` and `MOVE CORRESPONDING` in COBOL is that `MOVE` transfers data from one variable to another directly, while `MOVE CORRESPONDING` transfers data between records by matching fields with the same names. `MOVE` requires exact variable names, while `MOVE CORRESPONDING` uses field names to align data automatically.

Ques:- Hi I am Rathnam, How To Remove the duplicates with out using remove duplicate stage in the datastage

Asked In :-

Right Answer:
You can remove duplicates in DataStage without using the Remove Duplicate stage by using the following methods:

1. **Sort Stage**: Sort the data based on the key columns and then use a Transformer stage to filter out duplicates by keeping only the first occurrence.

2. **Aggregator Stage**: Use the Aggregator stage to group by the key columns and select the first or last occurrence of other columns.

3. **Join Stage**: Join the dataset with itself on the key columns and filter out duplicates based on a condition.

Choose the method that best fits your data flow and requirements.

Ques:- public static void main(String args[]) describe it

Asked In :-

Right Answer:
`public static void main(String args[])` is the entry point of a Java application. It is a public method, meaning it can be accessed from anywhere, static so it can be called without creating an instance of the class, and it takes an array of `String` arguments that can be used to pass command-line arguments to the program.

Ques:- what is difference between object oriented programming structure and object oriented programming system?

Asked In :-

Right Answer:
Object-Oriented Programming Structure (OOPS) refers to the conceptual framework and principles of organizing code using objects, such as encapsulation, inheritance, and polymorphism. Object-Oriented Programming System (OOPS) refers to the actual implementation of these principles in a programming language or environment that supports object-oriented features, allowing developers to create software using those concepts.

Ques:- Write a program that: Inputs two integers representing the sides of a triangle: a and b. Then, write a function which accepts the two sides as parameters and returns the hypotenuse of the triangle, c. Use the formula: c² = a² + b² 📌 JavaScript functions to use: To raise a number to a power: Math.pow(x, 5); → raises x to the 5th power. To find the square root: Math.sqrt(x); 📌 Requirements: You must create two functions: A main function that is called from a button click. A hypotenuse function that computes and returns the result. The main function: Gets the user’s input, Calls the hypotenuse function, and Outputs the result. Create your own CSS layout for the page.

The Programming Languages category on takluu.com is crafted for aspiring and experienced developers who want to showcase their core coding abilities during interviews. This section focuses on popular programming languages such as C, C++, Java, Python, JavaScript, Ruby, PHP, Go, Swift, and many others.

Programming languages are the fundamental building blocks for software and application development. Whether you’re building a mobile app, a cloud-based platform, or an embedded system, understanding how to write clean, efficient, and maintainable code is crucial. Interviewers often evaluate a candidate’s fluency in language syntax, data structures, object-oriented programming (OOP), memory management, error handling, and algorithmic problem-solving.

In this category, you’ll explore language-specific questions, including basic to advanced syntax, real-world coding challenges, debugging exercises, and performance optimization techniques. We cover best practices, design patterns, and language-specific nuances that often become deciding factors in technical interviews.

Additionally, many top tech companies emphasize problem-solving using a language of your choice, so the more comfortable you are with one or more languages, the better your chances of cracking the interview.

Whether you’re a beginner trying to master Python or an experienced developer preparing for system-level C++ interviews, this category has tailored resources to help you practice, revise, and get confident. You’ll also find tips on when to use which language, comparisons between programming paradigms, and key insights into what recruiters look for in language-specific roles.

By leveraging this category, you’ll be well-prepared for interviews ranging from junior software roles to senior backend engineers, mobile developers, and even full-stack specialists.
