High level languages are programming languages that are designed to be more user-friendly and easier to read and write than low level languages, which are more closely tied to the hardware of the computer. Many high level languages support object-oriented programming (OOP), which is a programming paradigm that focuses on creating reusable code components called objects.

In terms of the future vision for high level languages, there is a strong emphasis on making them more versatile and adaptable to changing technology. This means that they will likely continue to support programs that have already been written, while also enabling developers to create new and innovative applications.

However, high level languages can be difficult for beginners to learn, as they often require a deep understanding of programming concepts and syntax. Additionally, while they are frequently used for applications, they may not always be the most user-friendly option, as they can be complex and require a lot of technical expertise to use effectively.
High-level languages, such as Java and C++, are widely used for application development as they support Object-Oriented Programming (OOP), a popular programming paradigm. However, both languages may not be considered user-friendly or suitable for beginners due to their complex syntax and concepts.

Despite their steep learning curve, these languages have strong future visions, ensuring that programs already written in them will continue to be supported and maintained. This long-term support makes them attractive choices for developers who need to create robust and scalable applications.

What is computer maintenance software ?

Software that centralises maintenance data and streamlines maintenance operations is known as a computerised maintenance management system, or CMMS. It aids in maximising the use and accessibility of tangible assets like machines, transportation, communications, plant infrastructures, and other assets. CMMS systems, also known as computerised maintenance management information systems (CMMIS), are used in the manufacturing, energy, transportation, building, and other sectors where physical infrastructure is essential.

The difference between using a superclass to initialize a subclass object and vice versa involves the concept of inheritance in object-oriented programming.

When a superclass is used to initialize a subclass object, it means that the subclass is inheriting properties and methods from the superclass. This is known as inheritance, where a subclass (derived class) can inherit features from a superclass (base class). The subclass can use, override, or extend these inherited properties and methods.

On the other hand, using a subclass to initialize a superclass object is not a valid approach. A superclass should not be aware of its subclasses, and it cannot access the properties or methods specific to its subclasses. This is because the superclass is a more general class, while subclasses are more specific and may have additional properties or methods that are not available in the superclass.

In summary, the difference between using a superclass to initialize a subclass object and vice versa is that the former represents inheritance, where the subclass inherits properties and methods from the superclass, while the latter is not a valid approach as a superclass should not access or depend on its subclasses.

Explanation:

Resource allocation is the process of assigning a portion of a resource's capacity to a certain task. A resource can be in one of three states of allocation: under allocated, fully allocated, and over allocated.

When a resource is under allocated, it means that not enough of its capacity has been devoted to the task. When a resource is fully allocated, it means that its capacity is completely devoted to the task. And when a resource is over allocated, it means that more of its capacity has been devoted to the task than it is actually able to handle.

Answer:

In this article, we will learn how to make a Hexagon using Turtle Graphics in Python. For that lets first know what is Turtle Graphics.

Turtle graphics

Turtle is a Python feature like a drawing board, which let us command a turtle to draw all over it! We can use many turtle functions which can move the turtle around. Turtle comes in the turtle library.The turtle module can be used in both object-oriented and procedure-oriented ways.

Some of the commonly used methods are:

forward(length): moves the pen in the forward direction by x unit.

backward(length): moves the pen in the backward direction by x unit.

right(angle): rotate the pen in the clockwise direction by an angle x.

left(angle): rotate the pen in the anticlockwise direction by an angle x.

penup(): stop drawing of the turtle pen.

pendown(): start drawing of the turtle pen.

Approach –

Define an instance for turtle.

For a hexagon execute a loop 6 times.

In every iteration move turtle 90 units forward and move it left 300 degrees.

This will make up Hexagon .

Below is the python implementation of above approach.

When the submitButton is clicked, the 'outputLabel' text is set to the value of the variable 'sum'. This is because the 'outputLabel' object is set to display the value of the 'sum' variable in the line: `set outputlabel r 's Text to by app variable sum`.

Before the submitButton is clicked, the 'sum' variable is initialized to 0 in the line: `initialize app r variable sum to 0`.Then, a loop is executed using the 'count with i from 1 to' statement. This loop performs an operation on the 'sum' variable in the line: `do change app variable sum`.
