Write a program that reads a string and outputs the number of times each lowercase vowel appears in it. Your program must contain a function with one of its parameters as a string variable and return the number of times each lowercase vowel appears in it. Also write a program to test your function. (Note that if str is a variable of type string, then str.at(i) returns the character at the ith position. The position of the first character is 0. Also, str.length() returns the length of the str, that is, the number of characters in str.)

{

  double temperatures[7][2];//defining a double array temperatures

  double lowAvg=0, highAvg=0;//defining a double variable

Explanation:

Answer:

Question 1: The pseudocode is as follows:

int n = 70;

   int intArray[n];

   for(int i = 0; i< n; i++){

       print("Input "+(i+1)+": ")

       input intArray[i];

   }

Question 2: Advantages of array

Explanation:

Question 1

This declares and initializes the length of the array

int n = 70;

This declares the array

   int intArray[n];

This iterates through the length of the array

   for(int i = 0; i< n; i++){

This prompts the user for inputs

       print("Input "+(i+1)+": ")

This gets input for each element of the array

       input intArray[i];

   }

Question 2

Indexing: Elements of the array can easily be accessed through the index of the element.

For instance, an element at index 2 of array intArray can be accessed using: intArray[2]

Multiple Values: This is illustrated in question 1 above where we used 1 array to collect input for 70 values.

2 dimensional inputs: Literally, this means that array can be used to represent matrices (that has rows and columns).

An illustration is:

intArray[2][2] = {[0,1],[3,5]}

The above array has 2 rows, 2 columns and 4 elements in total.

d. RAID 6

Explanation:

RAID is a data storage technology that combines multiple physical disk drive components into a single logical unit. The functions of RAID is to provide performance and redundancy.

RAID 0 provides data stripping but it does not offer data stripping.

RAID 1 increases performance to about 2x but it limits the disk capacity to about 50%

RAID 5 provides redundancy and increased perfomance but it is limited to small disk drive.

RAID 6 also provides redundancy but it slows performance

RAID 10 increases performance and data protection.

RAID 6 is the best drive that offers redundancy over performance.

Absolute reference is used especially to keep the value or content of a column or row constant.

Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.

In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.

i. relative referencing

ii. absolute referencing

iii. mixed referencing

Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.

Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.

Mixed reference is a hybrid of the relative and absolute references.

A computer monitor is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.

A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.

Speakers receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.

A. Backstage view indox

Explanation:

Answer:

The method in Java is as follows:

public static char letterGrade(int average){

    char grade =' ';

    if(average>= 90 && average <=100){ grade ='A'; }

    else if(average>= 80 && average <=89){ grade ='B'; }

    else if(average>= 70 && average <=79){ grade ='C'; }

    else if(average>= 60 && average <=69){ grade ='D'; }

    else if(average>= 0 && average <=59){ grade ='F'; }

    return grade;

}

Explanation:

This defines the method

public static char letterGrade(int average){

This initializes the grade to a blank

    char grade =' ';

If average is between 90 and 100 (inclusive), grade is A

    if(average>= 90 && average <=100){ grade ='A'; }

If average is between 80 and 89 (inclusive), grade is B

    else if(average>= 80 && average <=89){ grade ='B'; }

If average is between 70 and 79 (inclusive), grade is C

    else if(average>= 70 && average <=79){ grade ='C'; }

If average is between 60 and 69 (inclusive), grade is D

    else if(average>= 60 && average <=69){ grade ='D'; }

If average is between 0 and 59 (inclusive), grade is F

    else if(average>= 0 && average <=59){ grade ='F'; }

This returns the grade

    return grade;

}

The question is incomplete. The complete question is :

Holly the Hacker has a list of 100,000 common passwords. She wants to use this list to break into UNIX-like systems that use a password file with lines consisting of:

The user's ID in plaintext.

10 bits of randomly chosen "salt," in plaintext.

The user's password, concatenated with the salt, and then encrypted.

There are very many such systems around the world, and Holly plans to steal the password files from as many as she can. The average system has 50 users in its password file.

Holly wants to create a master list of the encrypted versions of all the 100,000 passwords on her list, encrypted with all possible salt values. To create this master list, approximately how many encryptions of a password-concatenated-with-salt would Holly have to perform?

A. 2 million

B. 5 million

C. 100 million

D. 1 million

Solution :

It is given that the hacker, Holly wants break into the  UNIX-like systems using 100,000 common passwords that she has on her list. The system has at an average of 50 users in the password files.

Therefore, to create a master list, Holly have to perform about 50 x 100,000 = 5,000,000 encryptions for the password concatenated-with-salt.

Thus the correct option is option (B).  5 million

Explanation:

In a functional component were specified variables of local scope, and those outside are defined of global scope. It shows that the local variables can be accessible within the specified function, whereas global variables can be accessed via all functions all through the code structure. The variable size is the code portion where the variable can be accessed.

Replace the comment with:

maxSum =FindMax(numA,numB)+FindMax(numY,numZ);

Explanation:

Required

The statement to add up the two maximum from the functions

To do this, we have to call FindMax for both arguments i.e.

FindMax(numA,numB) and FindMax(numY,numZ) respectively

Next, use the + sign to add up the returned value.

So, the complete statement is:

maxSum =FindMax(numA,numB)+FindMax(numY,numZ);
