Answer: E) Input validation

              C) Data validation

Explanation:

  • Input validation is the process of analyzing and testing input's quality and correctness that are being processed at further level in information system.It help in eliminating any type of improper or informal input data from getting supplied to user or program in a system.
  • Input validation is also known as data validation.As the input that is being tested and validated is form of data that is going through cleansing task to remove useless data.
  • According to the question, data and input are being inspected to extract the validity and correctness of it before sending it for computation .Thus , both data and input validation is happening in this case.
  • Other options are incorrect because testing is examining the data.Correction data and input is the step for rectifying the mistakes in data or input.
  • Thus, the correct option is option(C) and (E).

Which number is equivalent to 3e-2?<br><br> 30<br><br> 0.03<br><br> 0.3<br><br> 3
nevsk [136]

Answer:

0.03

Explanation:

3e-2 is in scientific notation, also known as standard form. Used to write large or small numbers in another way. In the number 3e-2, the numbers are defined as follows:

3 = coefficient

e = 10 to the power of

-2 = exponent

The scientific notation 3e-2 is same as 3 x 10^-2 or 3 x 10-2. Thus, to get the answer to 3e-2 as a decimal, we multiply 3 by 10 to the power of -2.

= 3e-2

= 3 × 10-2

= 0.03

1. Name a two methods for creating text in Adobe Illustrator.
Fittoniya [83]

Answer:

Point type is a horizontal or vertical line of text that begins where you click and expands as you enter characters. Each line of text is independent—the line expands or shrinks as you edit it, but doesn’t wrap to the next line. Entering text this way is useful for adding a few words to your artwork.

Select the Type tool  or the Vertical Type tool .

The pointer changes to an I-beam within a dotted box. The small horizontal line near the bottom of the I-beam marks the position of the baseline, on which the text rests.

(Optional) Set text-formatting options in the Control panel, Character panel, or Paragraph panel.

Click where you want the line of text to begin.

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.

A source A producing fixed-length cells is required to use a Token Bucket Traffic Shaper (TBTS) of bucket capacity b=20 cell tok
makvit [3.9K]

Answer:

Please find the detailed answer as follows:

Explanation:

Long-term average cell rate is also called as sustained cell rate(SCR). It can be defined as the maximum average cell rate in a log time period(T).

The relation among the SCR, Average cell rate and Peak cell rate is as follows:

Avg.cell rate ≤ SCR ≤ PCR

If the source producing fixed-length cells at constant rate, then the long-term average cell rate will be same as peak cell rate(PCR).
