Write a function named word_beginnings that has two parameters line a string ch a character Return a count of words in line that start with ch. For the purposes of this exercise a word is preceeded by a space. Hint: add a space to the beginning of line For example if line is 'row row row your raft' and ch is 'r' the value 4 will be returned. Note: You can use lists in this question but try to solve it without lists.

Answers

Answer:

The function in Python is as follows:

def word_beginnings(line, ch):

   count = 0

   lines =line.split(" ")

   for word in lines:

       if word[0] == ch:

           count+=1

   return count

Explanation:

This defines the function

def word_beginnings(line, ch):

This initializes count to 0

   count = 0

This splits line into several words

   lines =line.split(" ")

This iterates through each word

   for word in lines:

This checks if the first letter of each word is ch

       if word[0] == ch:

If yes, increment count by 1

           count+=1

Return count

   return count

Dexter is trying to draw a rhombus and play the pop sound at the same time in his program. How should he correct the error in this algorithm? When space key pressed, draw rhombus, play pop sound.

This is absolutely true. A shining example of this is with smartphones.

Consider the following incomplete method. Method findNext is intended to return the index of the first occurrence of the value val beyond the position start in array arr. I returns index of first occurrence of val in arr /! after position start; // returns arr.length if val is not found public int findNext (int[] arr, int val, int start) int pos = start + 1; while condition '/ ) pos++ return pos; For example, consider the following code segment. int [ ] arr {11, 22, 100, 33, 100, 11, 44, 100); System.out.println(findNext (arr, 100, 2)) The execution of the code segment should result in the value 4 being printed Which of the following expressions could be used to replace /* condition */ so that findNext will work as intended?
(A) (posarr.length) &&(arr [pos]- val)
(B) (arr [pos] != val) && (pos < arr. Îength)
(C) (pos (D) (arr [pos} == val) && (pos < arr. length)
(E) (pos

Answers

Answer:

B)

Explanation:

The while loop runs as long as two conditions are satisfied, as indicated by the && logical operator.

The first condition- arr[pos] != val

checks to see if the value in the array index, pos, is equal to the given value and while it is not equal to it, the second condition is checked.

The second condition(pos < are.length), checks to see if the index(pos) is less than the length of the array. If both conditions are true, the program execution enters the while loop.

The while loop is only terminated once arr[pos] == Val or pos == arr.length.

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.

As of Spring 2020, in otder to get into the CS major, you must have a 3.0 GPA or better in cs120, cs210, and cs245. In this problem, you should write one function named get_gpa, which will calculate this GPA. This function should have one parameter, which will be a dictionary of grades in computer science courses. You can assume that the dictionary will always have the keys 'cs120', 'cs210', and 'cs245', but it also might contain some names of other courses too. The values associated with each key will be a float representeing the GPA-style grade for that class. For instance, the parameter dictionary might look like: {'cs120':4.0 'cs245':3.0, 'cs210':2.0}. Some examples:

get_gpa({'cs110': 4.0, 'cs245':3.0, 'cs335':4.0, 'cs120':3.0, 'cs210':3.0}) should return 3.0.
get_gpa({'cs110': 4.0, 'cs120':3.0, 'cs245':2.0, 'cs210':1.0}) should return 2.0.
get_gpa({'cs245':4.0, 'cs120':3.0, 'cs245':2.0}) should return 3.0.

Make sure to include only the one function in your file.

Answers

Answer:

The function is as follows:

def get_gpa(mydict):

   gpa = 0

   kount = 0

   for course_code, gp in mydict.items():

       if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':

           gpa += float(gp)

           kount+=1

   

   return (gpa/kount)

Explanation:

This defines the function

def get_gpa(mydict):

This initializes gpa to 0

   gpa = 0

This initializes kount to 0

   kount = 0

This iterates through the courses

   for course_code, gp in mydict.items():

If course code is cs120 or cs210 or cs245

       if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':

The gpa is added

           gpa += float(gp)

And the number of courses is increased by 1

           kount+=1

This returns the gpa    

   return (gpa/kount)

The Painting Company has determined that for every 112 square feet of wall space:
One gallon of paint at $9.53 per gallon is required if total square feet is 2000 or less. If square footage is greater than 2000, paint is $10.50 per gallon.
8 hours of labor at $35 per hour is required.
A hazardous material disposal fee of 7.5% of the total paint cost is required.
Create a function called paintJobCost which allows the user to provide the total number of square feet for the paint job and produces an itemized list of charges that includes:
Number of gallons of paint required.
Total Cost of the Paint (Paint Cost x Gallons Required)
Hours of labor required to paint (8 hrs per 112 sq ft)

Explanation:

For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.

During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.
