zhannawk [14.2K]

Answer:

Write a recursive, bool-valued function, containsVowel, that accepts a string and returns true if the string contains a vowel. A string contains a vowel if: The first character of the string is a v…

Explanation:

A:

bool containsVowel (string s) { bool hasVowel=false; if (s.length()==0) return false; else if (s[0]=='a'|| s[0]=='e'|| s[0]=='u'|| s[0]=='o'|| s[0]=='i'|| s[0]=='A'|| s[0]=='E'|| s[0]=='U'|| s[0]=='O'|| s[0]=='

Compare and contrast hardware and software.

lesya692 [45]

Hardware:
-physical parts of a computer that cause processing of data
-can be connected (physically) & can touch
- Hardware wares out during/over time
-Hardware failure is random
Software:
-A set of construction that tells a computer exactly what to do
-software is logical in nature
- dose not have an increasing failure rate

Similarities
- Behavior; Users interact with the products in various ways

- Products produce outputs and given inputs

-they have functional (user facing) and non functional (non user facing) requirements

-They are both complex (any representation of product specifications lead to a main structure)

Differences
- Software is easier to change then hardware

- Software testing is done by specialized quality assurance (QA) engineers, while hardware is done by engineers who are creating the product

-Hardware must be designed and tested to work over a range of time and environmental conditions, which is not the case for software

- Hardware designs are constrained by the need to incorporate standard parts

(Hope this helps?)

Convert the following numbers from decimal to binary, assuming unsigned binary representation:________.

kumpel [21]

Answer:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000

Explanation:

The method to generate the binary number from a decimal is :

Keep on dividing the number by 2 and keep on tracking the remainder

And the quotient is again divided and remainder is tracked so that the number is completely divided.

And then write the binary digits from bottom to top.

Please have a look at the method in below examples:

A) 35

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 35 & 1 \\ 2 & 17 & 1 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1\end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary number is 100011

B) 3

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 3 & 1 \\ 2 & 1 & 1 \\ \end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 11.

C) 27

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 27 & 1 \\ 2 & 13 & 1 \\ 2 & 6 & 0 \\ 2 & 3 & 1 \\ 2 & 1 & 1 \end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 11011.

D) 16

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 16 & 0 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1 \\\end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 10000.

Answers are:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000
