The programmer must initialize variables when they are declared

lorasvet [3.4K]

Answer: When you declare a variable, you should also initialize it. Two types of variable initialization exist: explicit and implicit. Variables are explicitly initialized if they are assigned a value in the declaration statement. Implicit initialization occurs when variables are assigned a value during processing.

Explanation:

For example, in JavaScript

var PaintAmount = 50; -declare and initialize

function setup() {

creatCanvas(200, 200);

}

function draw() {

ellipse(PaintAmount, PaintAmount) -use the variable PaintAmount

}

or rather in Java,

package random;

public class something() {

Public static void Main(String []args) {

string name; // this is declaring the variable with the example type

string name = new string; //this initializes the declared variable

}

What is the output of this program ? Assume the user enters 3,6 and 11

Nostrana [21]

Answer:

C++

Explanation:

C++ Standards

C++ is standardized as ISO/IEC 14882. Currently, there are two versions:

C++98 (ISO/IEC 14882:1998): First standard version of C++.

C++03 (ISO/IEC 14882:2003): minor "bug-fix" to C++98 with no change to the language. Commonly refer to as C++98/C++03 or First C++ standard.

C++11 (ISO/IEC 14882:2011): Second standard version of C++. Informally called C++0x, as it was expected to finalize in 200x but was not released until 2011. It adds some new features to the language; more significantly, it greatly extends the C++ standard library and standard template library (STL).

C++14: Infomally called C++1y, is a small extension to C++11, with bug fixes and small improvement.

C++17: informally called C++1z.

C++2a: the next planned standard in 2020.

C++ Features

C++ is C. C++ supports (almost) all the features of C. Like C, C++ allows programmers to manage the memory directly, so as to develop efficient programs.

C++ is OO. C++ enhances the procedural-oriented C language with the object-oriented extension. The OO extension facilitates design, reuse and maintenance for complex software.

Template C++. C++ introduces generic programming, via the so-called template. You can apply the same algorithm to different data types.

STL. C++ provides a huge set of reusable standard libraries, in particular, the Standard Template Library (STL).

C++ Strength and Pitfall

C++ is a powerful language for high-performance applications, including writing operating systems and their subsystems, games and animation. C++ is also a complex and difficult programming language, which is really not meant for dummies. For example, to effectively use the C++ Standard Template Library (STL), you need to understand these difficult concepts: pointers, references, operator overloading and template, on top of the object-oriented programming concepts such as classes and objects, inheritance and polymorphism; and the traditional constructs such as decision and loop. C++ is performance centric. The C++ compiler does not issue warning/error message for many obvious programming mistakes, undefined and unspecified behaviors, such as array index out of range, using an uninitialized variable, etc, due to the focus on performance and efficiency rather than the ease of use - it assumes that those who choose to program in C++ are not dummies.

Lindsey also needs to calculate the commissions earned each month. If the company earns $200,000 or more in a month, the commiss

lutik1710 [3]

Answer:

I have created and attached an image with example values for this question.

First we'll learn the IF function syntax:

IF(logical_test, value_if_true, [value_if_false])

Where

logical_test is the decision making comparison

value_if_true is the result to return when TRUE

value_if_false is the result to return when FALSE

We assume that cells B10 to G10 contain the Total Sales for January to June. And cells B17 to G17 contain the Commissions for January to June.

a.

The formula to use in cell B17 is:

=IF(B10>=200000;True;False)

b.

The formula to use in cell B17 is:

=IF(B10>=200000;B10*0.35;False)

c.

The formula to use in cell B17 is:

=IF(B10>=200000;B10*0.35;B10*0.27)

d.

To copy the formula in B17 to C17:G17, you can just copy and paste or select cell B17 and drag from the black square on the bottom right of the cell.

What is decorator and how to use it wit Python programming language?

SCORPION-xisa [38]

Answer:

Decorators are very powerful and useful tool in Python since it allows programmers to modify the behavior of function or class. Decorators allow us to wrap another function in order to extend the behavior of wrapped function, without permanently modifying it.
