Answer : 4. "all of the above"
Explanation :

An array is used to store values in memory. Arrays allow you to store multiple values of the same data type under a single variable name, making it easier to manage and manipulate data in programming. Arrays are commonly used in various programming languages for tasks such as storing collections of data, performing calculations on large sets of values, and iterating through elements to process them. Arrays are not used for deleting values in memory or for output; their primary purpose is to store and organize data.

Answer : 3. "Switch Statement"
Explanation :

The break statement is used with loops (such as for and while loops) and switch statements in programming. In loops, it is used to exit the loop prematurely, while in a switch statement, it is used to exit the switch block after executing a specific case.


Q:

What is it called when more than one if-statement is used together?

Answer : 2. "nested statement"
Explanation :

Certainly! A nested if statement refers to an if statement that is placed inside another if statement or other control structures. It allows for more specific conditions and complex decision-making in a program. The inner if statement is only executed if the outer if statement's condition is true.

Answer : 3. "Science"
Explanation :

FORTRAN (short for "Formula Translation") is a high-level programming language that is particularly well-suited for scientific and engineering applications. It was developed for numeric and scientific computing and is widely used in fields such as physics, engineering, mathematics, and other scientific disciplines. FORTRAN allows for efficient processing of mathematical and scientific computations, making it a popular choice for complex scientific simulations, mathematical modeling, and computational research.

Answer : 1. "Professional work"
Explanation :

COBOL (Common Business Oriented Language) is a high-level programming language primarily used for business, finance, and administrative systems within companies and governments. It is particularly useful for handling large-scale, data-centric applications in areas such as accounting, payroll, inventory management, and other business-related tasks. COBOL is known for its readability and ease of use, making it suitable for professionals working on applications that require extensive data processing and business logic. Despite being an older language, COBOL continues to be used in many legacy systems, especially in industries where stability and reliability are paramount.

Answer : 1. "BASIC"
Explanation :

The language considered the "foundation stone" for teaching languages like FORTRAN, ALGOL, PASCAL, and many others is ALGOL (Algorithmic Language). ALGOL was a significant early programming language that influenced the design of subsequent programming languages, providing important concepts and structures used in the development of languages like FORTRAN, PASCAL, and C. While BASIC is also a widely used beginner-friendly programming language, ALGOL had a substantial impact on the development of programming language theory and design.

Answer : 3. "parsing"
Explanation :

Parsing, in high-level language transformation, is the analysis of code syntax using formal grammar rules. It checks for errors and creates a parse tree representing the code's structure. This tree guides the generation of machine code or program execution, ensuring correct interpretation and execution of the source code.
