import java.util.Scanner;

public class U2_L3_Activity_Four {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter a sentence.");

String sent = scan.nextLine();

int count = 0;

for (int i = 0; i < sent.length(); i++){

char c = sent.charAt(i);

if (c != ' '){

count++;

}

else{

break;

}

System.out.println("The first word is " + count +" letters long");

}

We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!

Your company wants to conduct an exploratory study to gain new insights into some product changes you are considering. Which typ

Lina20 [59]

Answer: Primary Research (Focus Group).

Explanation:

Exploratory Research is an inquiry that seeks to understand the basic causal factors of a problem. This effort can serve as the basis of more intensive research later on.

There are basically two methodologies used, which are the; Primary and Secondary methods. While the Primary method's source of information is the concerned group, the Secondary Methods obtain their information from already existing information (Primary sources), such as Interviews, Journals, etc.

In the case of the company in the question, seeking to gain insight into the changes in a product, it would be best for them to consider what some selected costumers (focus group), think about the existing products and their views on subsequent changes. This method of getting information directly from the focus group employs the primary method.

professor190 [17]

<span>I can't imagine any reason "why" he should have behaved in such an extraordinary way. If we were to use "how" in that sentence it would contradict the context. We are obviously talking about a situation that has happened so we know that "he" has in fact acted in an extraordinary way but we don't know "why" he acted that way. Therefore "why" is the correct term to use.</span>

A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a fi

victus00 [196]

Answer:

I am writing a Python program.

def concordance(filename): # function that takes a file name as parameter and returns the concordance for that file

file = open(filename,"r") #opens file in read mode

unique={} #creates and empty list

for word in file.read().split(): #loops through every word in the file

if word in unique: # if words is already present in the list

unique[word] += 1 #add 1 to the count of the existing word

else: #if word is not present in the list

unique[word] = 1 #add the word to the list and add 1 to the count of word

file.close(); # close the file

for x in sorted(unique): #sort the list and displays words with frequencies

print(x, unique[x]); #prints the unique words and their frequencies in alphabetical order

#prompts user to enter the name of the file

file_name=input('Enter the input file name: ')

concordance(file_name) #calls concordance method by passing file name to it

Explanation:

The program has a function concordance that takes a text file name as parameter and returns a list of unique words and their frequencies.

The program first uses open() method to open the file in read mode. Here "r" represents the mode. Then creates an empty list named unique. Then the for loop iterates through each word in the file. Here the method read() is used to read the contents of file and split() is used to return these contents as a list of strings. The if condition inside the loop body checks each word if it is already present in the list unique. If the word is present then it adds 1 to the count of that word and if the word is not already present then it adds that unique word to the list and assign 1 as a count to that word. close() method then closes the file. The second for loop for x in sorted(unique): is used to display the list of unique words with their frequencies. sorted() method is used to sort the list and then the loop iterates through each word in the list, through x, which acts like an index variable, and the loop displays each word along with its frequency.

Write a function called sum_scores. It should take four arguments, where each argument is the team's score for that quarter. It

saw5 [17]

Answer:

Here is the Python program which has a function sum_scores:

def sum_scores(score1, score2, score3, score4):

sum = score1 + score2 + score3 + score4

print(sum)

sum_scores(14,7,3,0)

Explanation:

Method sum_scores takes four arguments, score1, score2, score3, score4.
The sum variable adds these four scores and stores the value of their addition.
Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
The output of the above program is:
24
If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
The program along with the output is attached as a screenshot.
