Create awk commands to remove all occurrences of the word "PCC" from the input
stream. Your output should be a copy of each input line, with the word PCC
removed wherever it occurs.

File: awk-utility-assessment-4.awk
Create awk commands to calculate the sum of all digits in the input.
For example, if the input contains the number 123 in the first line,
and the number 456 in the last line, the output should be 21.
Your output should be a single number.

Write a program to output to a text log file a new line starting with day time date followed by the message "SUCCESSFUL".

Please screenshot the results.

Use DevC++ to implement a program that can store and output 5 integers, where the user can input its value into an array named arrayValue. The program should implement the following:

1. Calculate the sum and average of the array.

2. Output the content (value) that stored in the array of five elements.

3. Continue to ask the user to store for storing data into another array.

c++ ONLY PLEASE NEED IT FAST AS POSSIBLE

Write a program named FinalExamProgram2 that reads numbers from a file (which you will create using Notepad) into a one-dimensional array and then analyzes the numbers as described below. Your program must use loops to read the numbers into the array and to analyze the contents of the array. The program’s main function should do the following:  Read eight floating-point numbers from the file named numbers.txt into a onedimensional array, displaying each number on the screen.  Pass the array to a function that finds and displays (on the screen) how many of the array’s elements are zero, how many are negative, and how many are positive. Display the number of zeroes first. Then display the other two counts in descending order. In other words, if there are more positives than negatives, display the number of positives before you display the number of negatives—and vice versa.  Pass the array to another function that finds and displays (on the screen) the average of the squares of the positive numbers and the average of the squares of the negative numbers. Display these averages in descending order. Your outputs should look exactly as shown on the next page (spelling, punctuation, spacing, number format, and so on).

Write a program to prompt the user to display the following menu:

Guess-Number                        Concat-names             Quit

• If the user selects Guess-number, your program needs to call a user-defined function called int guess-number ( ). Use random number generator to generate a number between 1 – 100. Prompt the user to guess the generated number and print the following messages. Print the guessed number in main ():

Guess a number: 76

96:

Too large

10

Too small

70

Close

Do you want to quit? Q

• If the user selects Concat-name, prompt the user how many names to concatenate and then enter all the first and las names and store then into a two one-dimensional array. Your program needs to call a user-defined function called void sort-name ( char [] , char[]) to concatenate the first name and the last name and print the names in this function.

How many names: 3

First name                   last name                                Combined

Sue                              Smith                                       Sue Smith

left = L[ 0 : len(L)//2 ]
right = L[ len(L)//2 : len(L) ]
return output + prob15(left) + prob15(right)

Use DevC++ to implement a program uses objected oriented programming to calculate the area of a rectangle. The program should create a Rectangle class that has the following attributes and member functions:

Attributes:
width and length

Member functions:
setWidth(), setLength(), getWidth() , getLength(), getArea()

Where width and length are the respect width and length of a Rectangle class. The setWidth() and setLength() member function should set the length and width, the getWidth(), getLenght(), and getArea() member function should get the length, width, and area. The program should

1. Ask the user for the length and width of rectangle.

2. Output the length, width, and area of a rectangle.

3. Continue to ask the user to calculate another rectangle area by asking length and width.

Design and implement a C++ program

• read in a whole line of characters as the input string;
• count and display how many times
• how frequently (among the letters) each (case insensitive) letter appears in the above mentioned input string;

Sample program execution:

An example of executing such a program is shown below. Note that the user input is in italic font.

Please enter a line of characters:
This is a really long line of characters!

There are 41 characters in the input line.
And among them, 33 are letters.

5. Differentiate between tech sector, STEM, and computer industry careers.

In C# A Tic Tac Toe program that uses functions and arrays. The program should start by asking the player one for their name and then player two for their name. Then should print the board and ask the user what column and then what row they would like to put their x (or o, depending on the player) . Use the clear function to make it look as though the board is never repeating.. Thanks!
